An analysis of frequency pulling in a varactor-tuned LC VCO under coupling from an on-chip PA is presented. The large-signal behavior of the VCO's inversion-mode MOS varactors is outlined, and the susceptibility of the VCO to frequency pulling from PA aggressor signals with various modulation schemes is discussed. We show that if the aggressor signal is aperiodic, band-limited, or amplitude-modulated, the varactor-tuned LC VCO will experience frequency pulling due to time-modulation of the varactor capacitance. However, if the aggressor signal has constant-envelope phase modulation, VCO pulling can be eliminated, even in the presence of coupling, through careful choice of VCO frequency and divider ratio. Additional mitigation strategies, including new inductor topologies and system-level architectural choices, are also examined. The analysis is then applied to improve a fully-integrated half-duplex UHF micro- transceiver in which signal coupling between the LO and PA caused frequency pulling that prevented the use of QPSK signaling at certain data rates. We determine that a VCO operating at 4x transmit frequency will be naturally insensitive to pulling from QPSK signals. To validate the proposed solution, a prototype IC containing a pair of QPSK transmitters with integrated 100mW Class-C PAs was designed and fabricated in 0.18um SOI. The transmitters--one utilizing a 2x VCO, one utilizing a 4x VCO-- were designed to closely match the performance of the original microtransceiver when transmitting QPSK data. The transmitter with the 2x VCO experienced frequency pulling from the PA while transmitting QPSK data, but the transmitter with the 4x VCO did not, thereby confirming the analysis in this work. A revision of the microtransceiver was designed in 0.5 [mu]m SOS utilizing an off- chip PA inductor to reduce signal coupling with the VCO. A second revision of the microtransceiver with two prototype transmitters was designed in 0.25 [mu]m SOS uti- lizing 4x VCOs and figure-8 VCO inductors for maximum insensitivity to pulling from QPSK and band-limited modulation, as well as other design improvements that leverage the higher f[subscript]t of the smaller process. Both revisions also include a hardware FSK modulator, a new charge pump, and a redesigned fractional-N synthesizer to attenuate a divided-reference spur in the IF output. These revisions of the radio will enable future researchers to focus on system-level applications where highly-integrated medium-power transceivers with fully-functioning IQ modulation are needed.

Texte intégralSince 1967, the definition of the second is based on the atomic properties of the 133Cs atom. The device that realises this definition is an atomic clock. In this work, we present the progress made in the last year on Brazilian scientific time and frequency program. The aim of this dissertation work is the caracterization of our standard. We report the major sifts present in our atomic clock due to Quadratic Zeeman effect, Δν/ν0 =5,4×10-13 Cavity Pulling, Δν/ν0 =1,27×10-13 Rabi Pulling, Δν/ν0 =1,3×10-13 and other ones, which induced a shift in the hiperfine levels frequency of the performances: a global uncertainty of 1,44×10-12 and a short term stability of 1,8×10-10Τ-0,5 .The results were obtained after these changes: we have determined the optimum microwave power injected into the cavity in order to increase the signal and assure that the atoms suffer a π/2 pulse; we have also minimizes the field inhomogeneity by improving the control of the static magntic field along the interaction region; we have decreased the temperature of the clock oven in order to obtain a slower atomic beam. All this changes has increased our accuracy and our stability of about one order.

This dissertation covers two main research topics. The first main research topic is to study the injection locking enhancement technique in CMOS injection-locked frequency divider (ILFD), which includes the dual-band operation of 30 GHz divide-by-three and 50 GHz divide-by-five ILFD. The ILFD can be applied to the proposed 28 GHz and 47 GHz frequency bands of the 5G mobile communication. The second main topic is to study the injection pulling mitigation technique in CMOS LC voltage-controlled Oscillator using a novel honeycomb-shaped planar inductor. The design of a divide-by-three frequency divider operating at 30 GHz with an injection- switched cross-coupled pair (IS-CPP) technique to enhance the locking range is reported in Chapter 2. A wider locking range as well as a lower operation voltage can be achieved because of this newly proposed topology. The divider is implemented in a 90 nm standard CMOS process. The total locking range of the divider core is 4.5 GHz with a power consumption of 2.85 mW from a supply voltage of 0.5 V. The total power consumption of the buffers is 2.65 mW from a supply voltage of 1.0 V. The measured output phase noise is -141 dBc/Hz at 1 MHz offset when the input referred signal with a phase noise of -131 dBc/Hz at 1 MHz offset from 30 GHz. The phase-noise difference of 10 dB is close to the theoretical value of 9.5 dB for division-by-three. The total chip size is 0.48 mm2 and the divider core size is only about 0.14 mm2. A CMOS 30 GHz divide-by-three ILFD using the IS-CCP technique can also operate at a divide-by-5 mode. The related experimental results to demonstrate the extra capability of the proposed divider as a 50 GHz divide-by-five ILFD. The total locking range of 2.4 GHz is available at 50 GHz with a total dc power dissipation of 5.5 mW. The measured output phase noise of -143 dBc/Hz is obtained from an input signal of -127 dBc/Hz at 1 MHz offset from 50 GHz. This divider can be applied to a millimeter-wave PLL design for 47 GHz radio band applications, which include the newly proposed frequency band for the 5G mobile communication. The last part of the dissertation presents the injection pulling mitigation technique applied to a voltage controlled oscillator (VCO) using a novel honeycomb-shaped planar inductor. Due to the twisted routes of the sub-coils in the proposed inductor, the interference caused by a nearby electromagnetic noise source can be compensated and reduced. By using a 0.18-μm standard CMOS process, the proposed honeycomb-shaped planar inductor and a conventional single-turn spiral inductor in a similar size are integrated into two respective VCO test chips. The injection pulling behaviors of these two oscillators are studied and compared. The experimental results show that the VCO integrated with the proposed honeycomb-shaped planar inductor can significantly mitigate the injection pulling phenomenon as compared to the VCO integrated with a conventional single-turn inductor in a similar size. In this study, the enhancement of mitigation over 15 dB can be achieved.

The purpose of this study was to investigate the effects of various combinations of the step frequency and length in Back Step motion on team''''s pulling force. The subjects were 8 female high school pullers. According to combinations of 4 kinds of step length(5cm/step, 10cm/step, 15cm/step, 20cm/step) and 4 kinds of step frequency (2step/sec, 1step/sec, 0.7step/sec, 0.5step/sec), subjects were asked to drag the pieces of iron on a derrick. One JVC digital camera(60Hz) was synchronized with a load cell(900Hz) that was inserted between the rope and the derrick to record images and the pulling force. The pulling force and images were digitized by Data Acquisition System Laboratory and Ariel Performance Analysis System, and the Microsoft Excel program was used for the basic data statistics. The results of data analysis were: 1.The maximum team''''s pulling force was increasing when the step length was increasing. 2.The minimum team''''s pulling force was decreasing with the decreasing step frequency. 3.The difference between the maximum and minimum team''''s pulling force was increasing when the step length increased and the step frequency decreased. 4.Without the maximum or minimum team''''s pulling force , the force of the right foot was almost greater than the left foot. Therefore, the team’s pulling force was greatly effected by different combinations of back step frequencies and lengths. The 0.7step/sec with 20cm/step and 2step/sec with 5cm/step were suggested to get the better pulling force and keep the attacking advantage for the tug-of-war pullers. Key words : tug of war, Back Step motion, step frequency, step length, team''''s pulling force
