Повний текст джерелаThe objective of this thesis is to study and design a digitally programmable delay locked loop for a UWB radar sensor in 0.13 m CMOS technology.. Almost all logic systems have a main clock signal in order to provide a common timing reference for all of the components in the system. In certain cases it is necessary to have rising (or falling) edges at precise time instants, different from the ones in the main clock. To create those new timing edges at the appropriate time it is necessary to use delay circuits or delay lines. In the case of the radar system its necessary to generate a clock signal with a variable delay. This delay is relative to the transmit clock signal and is used to determine the target distance. Traditionally, delay lines are realized using a cascade of delay elements and are typically inserted into a delay-locked-loop (DLL) to guaranty that the delay is not affected by process and temperature variations. A DLL works in a similar way to a Phase Locked Loop (PLL). In order to facilitate the operation of the radar system, it is important that the delay value should be digitally programmable. To achieve a digitally programmable delay with a large linearity (independent from matching errors), the architecture of the system is constituted by a digital modulator that controls a 1-bit digital to time converter, whose output will be filtered by the DLL, thus producing the delayed clock signal. The electronic sub-blocks necessary to build this circuit are describe in detail as the proposed architectures. These circuits are implemented using differential clock signals in order to reduce the noise level in the radar system. Design and simulation results of the digitally programmable DLL shows a high output jitter noise for large delays. In order to improve this results a new architecture is proposed. Conventional DLL’s have a predefined charge pump current. The new architecture will make the charge pump current variable. Simulations results will show a improved jitter noise and delay error.

Charge pump has developed for thirty years from 1976 till now. However, different kinds of charge pump have their advantages and disadvantages. The biggest problem among these charge pump circuits is that most of these charge pumps would cause voltage gain and efficiency lower than the ideal values due to the undesired loss. In this thesis, the disadvantage that charge pump circuits are alleviated and a new cross-coupled charge pump circuit is presented to enhance the performance of energy loss. Till now, most charge pumps all have the same problems such as, threshold voltage drop, body effect, gate-oxide reliability, reversion loss, conduction loss and redistribution loss. These problems may cause the layer of gate-oxide broken and the system failure. Besides, the breakdown not only makes damage to MOS transistors but also decreases voltage gain and, thereby diminishing conversion efficiency of charge pump. Therefore, the most important things that the designers need to do are to minimize the effects of these disadvantages. The cross coupled charge pump mentioned in this thesis will improve or alleviate the above problems and thus increase the efficiency of charge pump circuits. The proposed technique can effectively avoid the energy loss in the operation of charge pump circuits. The test chip was designed by TSMC 0.35um technology. Simulation results can demonstrate the correctness and performance of the proposed techniques.

Power efficiency is an important issue for portable electronic devices. The major part of power consumption of portable device is LED backlight module. Therefore, deign of high efficiency backlight module is required to extend the operation time. Nowadays white light-emitting diodes (WLEDs) have replaced cold cathode fluorescent lamps (CCFL) as backlight modules in portable electronics in terms of power efficiency and size. This paper presents a current mode DC-DC converter for WLED and OLED that are all popular light source for portable devices.

A self-regulated charge pump circuit is proposed. The charge pump exploits an automatic pumping control scheme to provide small output ripple voltage. The automatic pumping control scheme is composed of two schemes, an automatic pumping current control scheme and an improved automatic pumping frequency control scheme. We utilized a Range-programmable Voltage-controlled Oscillator which has four different frequency band outputs depended on load current value. The output frequency of the VCO varies from 400KHz to 10MHz. The improved automatic pumping frequency control scheme generates high pumping frequency when the system provides the great load current, and also reduce the output ripple voltage. The improved charge pump is designed in a TSMC 0.18 CMOS process. The fabricated circuit occupies an area of 734.54um*794.805um, operating at 1.8V power supply with a flying capacitor of 330nF. For the variable load resistor and the load capacitor of 2μF. The circuit offers load current from 1mA to 30mA. The improved charge pump delivers 2.05-V output voltage, and the output ripple voltage is less than 1mV, and the power efficiency is 51.5%, while providing 30mA of load current.

Charge pump circuits (CPCs) are commonly used for pumping charge upward to produce higher than the regular supply voltage or downward to negative voltage on a chip, and have been widely used in non-volatile memories (NVMs) for many years since the NVMs require a high voltage to program floating-gate devices. Power integrity has become more important as scaling down the supply voltage in SOC designs, the largest power noise and ground bounce occur in high voltage generator as CPC for embedded NVMs such as Flash memory, OTP and EEPROM since periodical switching clock s cause serious power peak current and suffer inductive effect on package bond wire. Suppressing power peak current (PPC) is the most key point for a low noise design. This study proposes new 4-phase with distributed local control scheme that each charge pump module operates not at the same time, therefore the peak current would be degraded and switching power noise due to dI/dt is greatly reduced The Low Noise Charge Pump (LNCP) is fabricated in 90nm CMOS technology. The measurement results demonstrate that the power noise can be reduced more than 60% from 10MHz to 16.7MHz and better power efficiency about 7% comparing to conventional 4-phase CP with less than 3% area penalty. Moreover, LNCP can be achieved to high speed with new 4-phase clock control in the future.
