碩士 === 國立臺灣海洋大學 === 電機工程學系 === 98 === Due to the rapid development and popularization of wireless technology and personal mobile communication in recent years, the performance of transceiver is more and more importance, and the voltage controlled oscillator will directly affect the transceiver’s performance. In this thesis, we investigate the design and applications of low-voltage and wide-band voltage-controlled oscillator (VCO) and frequency synthesizer. We have designed four VCOs and one frequency synthesizer using TSMC 0.18μm 1P6M MOS process. Low-Voltage Wide-Tuning-Range X-Band Complementary Voltage Controlled Oscillator：The measurement shows that the supply voltage is 1.4 V and output frequency is 9.47 GHz. The phase noise at 1 MHz offset is -109.4 dBc/Hz. The total power dissipation is 18.5 mW and VCO core consumption is 14.5 mW. The operation frequency is 8.66-10.21 GHz and tuning range is 1550 MHz. The chip size including pad is 0.931*0.707 mm2. Design of a High Performance Low Phase Noise VCO：The measurement shows that the supply voltage is 0.8 V and output frequency is 4.25 GHz. The phase noise at 1 MHz offset is -128.75 dBc/Hz. The total power dissipation is 14.3 mW and VCO core consumption is 8.84 mW. The operation frequency is 4.248-4.416 GHz and tuning range is 168 MHz. The chip size including pad is 0.85*0.81 mm2. Ultra-Low-Power-Consumption Wide-Tuning-Range Voltage- Controlled Oscillator Using Body-Biasing Technique：The measurement shows that the supply voltage is 0.5 V and output frequency is 5.1 GHz. The phase noise at 1 MHz offset is -112.2dBc/Hz. The power dissipation is 2.54 mW. The operation frequency is 4.9-5.37 GHz and tuning range is 467 MHz. The chip size including pad is 0.53*0.9 mm2. Improving Phase Noise of Low-Voltage Ku-Band VCO Using Capacitor Feedback Technique：The simulation shows that the supply voltage is 0.8 V and output frequency is 13.27 GHz. The phase noise at 1 MHz offset is -115.7 dBc/Hz. The total power dissipation is 12 mW and VCO core consumption is 6.6 mW. The operation frequency is 12.78-14.05 GHz and tuning range is 1274 MHz. The chip size including pad is 0.58*0.88 mm2. Low-Voltage Low-Noise Dual-Band Frequency Synthesizer：The measurement shows that the supply voltage is 1.2 V and output lower and higher frequencies are 2.3 GHz and 3.15 GHz, respectively. The phase noises at 1 MHz offset of both bands are -115 dBc/Hz and -114 dBc/Hz, respectively. The power dissipation is 24.6 mW for operation frequencies of 2.26-2.45 GHz and 3.07-3.33 GHz. The locking time is smaller than 8 μs and the chip size including pad is 1.4*1.4 mm2.
