摘要

采用0.35 /spl mu/m的BiCMOS工艺设计了一种10 GHz的CMOS分布式压控振荡器(DVCO)。该振荡器的调谐范围为12% (9.3 GHz至10.5 GHz)，在10.2 GHz载波频率偏移1mhz时相位噪声为-114 dBc/Hz。VCO使用两种不同的同步调谐技术，允许在频率合成器中对频率进行粗调和微调。该振荡器的输出功率为-7 dBm，无任何缓冲，从2.5 V电源中吸取14 mA的直流电流。

A 10 GHz CMOS distributed voltage controlled oscillator

A 10 GHz CMOS distributed voltage controlled oscillator (DVCO) is designed in a 0.35 /spl mu/m BiCMOS process technology using only CMOS transistors. The oscillator achieves a tuning range of 12% (9.3 GHz to 10.5 GHz) and a phase noise of -114 dBc/Hz at 1 MHz offset from a carrier frequency of 10.2 GHz. The VCO uses two different simultaneous tuning techniques which allow for a coarse and fine tuning of frequency in a frequency synthesizer. The oscillator provides an output power of -7 dBm without any buffering, drawing 14 mA of DC current from a 2.5 V power supply.
