Introduction -- Design theory and process technology -- 15GHz oscillator implementations -- 24GHz oscillator implementation -- Frequency prescaler implementation -- MMIC fabrication and measurement -- Conclusion.
Advances in Silicon Germanium (SiGe) Bipolar Complementary Metal Oxide Semiconductor (BiCMOS) technology has caused a recent revolution in low-cost Monolithic Microwave Integrated Circuit (MMIC) design. -- This thesis presents the design, fabrication and measurement of four MMICs for frequency synthesis, manufactured in a commercially available IBM 0.18μm SiGe BiCMOS technology with ft = 60GHz. The high speed and low-cost features of SiGe Heterojunction Bipolar Transistors (HBTs) were exploited to successfully develop two single-ended injection-lockable 15GHz Voltage Controlled Oscillators (VCOs) for application in an active Ka-Band antenna beam-forming network, and a 24GHz differential cross-coupled VCO and 1/6 synchronous static frequency prescaler for emerging Ultra Wideband (UWB) automotive Short Range Radar (SRR) applications. -- On-wafer measurement techniques were used to precisely characterise the performance of each circuit and compare against expected simulation results and state-of-the-art performance reported in the literature. -- The original contributions of this thesis include the application of negative resistance theory to single-ended and differential SiGe VCO design at 15-24GHz, consideration of manufacturing process variation on 24GHz VCO and prescaler performance, implementation of a fully static multi-stage synchronous divider topology at 24GHz and the use of differential on-wafer measurement techniques. -- Finally, this thesis has llustrated the excellent practicability of SiGe BiCMOS technology in the engineering of high performance, low-cost MMICs for frequency synthesis in millimeterwave (mm-wave) devices.

Las propiedades de los dispositivos microfluídicos tales como el procesamiento rápido de las muestras y el control de los fluidos, les han hecho atractivos candidatos para reemplazar los tradicionales métodos experimentales. Los dispositivos microfluídcos están caracterizados por canales fluídicos con dimensiones del orden de decenas a centenares de micrómetros. Las estructuras con estos tamaños permiten la integración de la tecnología "lab-on-chip", la cual permite el procesamiento de dispositivos miniaturizados para el control y la manipulación de fluidos. La detección de fluidos a través de sensores de microondas basados en el análisis de radiofrecuencia ofrece nuevas posibilidades para la caracterización de medios a través de métodos no invasivos. Las medidas dieléctricas de los fluidos son importantes debido a que pueden proporcionar información las características eléctricas o magnéticas de los materiales, siendo útil en muchos campos de investigación y desarrollo tales como biología molecular o para realizar diagnósticos médicos. En el dominio frecuencial, varias tecnologías están disponibles en el mercado para analizar las propiedades dieléctricas y la composición de los líquidos. En esta tesis, estamos enfocados en las técnicas basadas en cavidades resonantes para la caracterización de fluidos en el rango de las ondas milimétricas. Sin embargo, estas técnicas son incompatibles con los procesos "lab-on-chip" debido a sus dimensiones en esta banda de frecuencia. En este contexto, una nueva estructura guía onda denominada "gap waveguide" aparece como un buen candidato para solventar los principales inconvenientes de las clásicas cavidades resonantes. En esta tesis se ha desarrollado la tecnología "gap waveguide" en la banda de ondas milimétricas. Otras tecnologías convencionales serán estudiadas para comparar el rendimiento de todas ellas en términos de pérdidas. También se presenta en esta tesis, el diseño de resonadores basados en la tecnología "gap waveguide" con el propósito de hacer esta tecnología compatible con la detección microfluídica. En este contexto, proponemos un estudio comparativo entre las tecnologías "gap waveguide" y "Substrate Integrated Cavity" (SIC) con el objetivo de caracterizar la permitividad de los fluidos a 60 GHz. Con este propósito, varios prototipos han sido fabricados usando las tecnologías PCB ("Printed Circuit Board") y LTCC ("Low Temperature Co-fired Ceramic". Un importante trabajo en el laboratorio LTCC se realizó para validar algunas de las etapas del proceso LTCC que eran la clave para la fabricación de prototipos basados en "gap waveguide", como la creación de cavidades (externas e internas) usando materiales LTCC.

In this thesis, the millimeter-wave radar sensor AWR1642 developed by Texas Instruments is used to realize the millimeter-wave radar system operating in the 77-81 GHz band. The raw data received by ADC of the radar chip is processed to obtain the position of objects. We design three experiments to measure the range resolution, the maximum detectable distance and the signal to noise ratio of received signal. Then, we analyze and discuss the results of these measurements separately. Finally, we conclude the limitations of range estimation in the application of millimeter wave radar systems.

The communication circuits applied in microwave and millimeter-wave frequency ranges have being gradually popularized in our life. Among the circuits, the oscillator constitutes an important circuit in the communication system. The injection-locked oscillator can improves the phase noise of the output signal by means of additionally injecting signals. This thesis explores the process and principle of the injection-locked oscillator and the deductions on the injection-locked oscillator models based on the relevant literatures. This thesis is mainly divided into two parts. In the first part, it explores how to make voltage-controlled oscillator at K-band by using SiGe BiCMOS technology and ADS simulation software. The variable capacitor is implemented by connecting the heterojunction bipolar transistor (HBT) and the metal-oxide-semiconductor field-effect transistor (MOSFET) in parallel.Thus, this oscillator shows a wide tuning range. The adjustable frequency range is from16.5 GHz to 19.85 GHz. In the second part of thesis, 50 GHz and 75 GHz subharmonic injection-locked oscillators are designed and manufactured in BiFET and GaAs pHEMT technologies. The measured oscillator shows low phase noise, wide-band locking range, low power consumption and high output power. Finally, this thesis explores how to use voltage-controlled oscillator to realize the modulation for the frequency-shift keying (FSK) signals and to demonstrate the demodulating the FSK signals using the injection-locked oscillator.

Pulse Doppler radar, which has a history of several decades, is most widely used in military applications, such as fire control radar, search radar, and tracking radar. These radars aim at detecting, searching, and tracking minatory target vehicle of enemies. According to the requirements of military combat, military radars must possess sufficient radiation power to detect targets from a far distance, such as fly bomb, flying vehicle, and naval vessels. The contemporary radar technology has evolved from simple radio frequency radar to phase-coded and infrared radars with an extended application in non-military monitoring, detection and security control, and regulation. In small areas, there is no need to use a large radiation power, resulting in dramatically reduced volume, which could play an important role in indoor security care and countering terrorism by detection and control. The objective of this study is to design a Self-spin RF Metal Detect System for regional use based on radar working principles for large-scale indoor security care and antiterrorism monitoring. Therefore, it monitors minatory metal objects (angles and distances) in large-scale indoor public areas, like public transportation places such as airports, subways, bus stations, and thus protects people’s life through rapid detection for potential risks.

In this dissertation, the first part is the design of a 60-GHz sub-harmonic RF receiver with an integrated on-chip artificial-magnetic-conductor (AMC) Yagi antenna and a balun bandpass filter (BPF) in 90-nm CMOS. This is to pursue RF system-on-chip for 60-GHz single-chip radio with on-chip antenna-filter integration of low-cost CMOS RF front-end circuitry for very-short-range (VSR) gigabit wireless communication. The AMC structure in the on-chip antenna is to reduce the CMOS substrate loss and increase the antenna radiation efficiency and power gain. The probe-station based on-wafer wireless digital-modulation wireless transmission test has been conducted. The measured maximum data rate is 1.152 Gb/s (approximately with a BER of 10-3) in 16QAM OFDM mode over a 25-cm distance. The chip size is 1.5×2 mm2 and the power consumption is 31 mW. For the second part, at first it is devoted to develop the V-band waveguide prototype of a 60-GHz vital-signs Doppler radar system or called millimeter-wave life detection system (MLDS). Then, a fully-integrated 60-GHz 90-nm CMOS direct-conversion Doppler radar RF sensor with clutter canceller circuits is designed for single-antenna noncontact human vital-signs detection. The clutter canceller can enhance the detecting sensitivity of weak vital signals. The on-wafer experimental measurements show clearly recorded waveforms of the heartbeat (1–1.3 Hz) and breathing signals (0.35–0.45 Hz) at a distance of 75 cm (with the chip connected through a 7-dB-loss V-band cable to a 17-dBi 60-GHz patch-array printed circuit board (PCB) planar antenna). The chip size is 2×2 mm2 and the power consumption is 217 mW. The presented integrated 60-GHz vital-sign RF sensor is devoted to be integrated in small portable communication devices (such as smartphone). It will be very useful for the wireless remote physiological monitoring healthcare and tiny vibration detecting applications.
