Abstract

This paper presents a novel inversion-mode three-terminal varactor with a capacitance ranging from 0.7 pF to 2.3 pF, achieving a /spl plusmn/53% variation in the capacitance. The new device is implemented in a 0.35-/spl mu/m standard CMOS process. The measured quality factor is 22 at 2 GHz. A 2-GHz VCO is designed with this new varactor and is able to achieve a tuning range of 320 MHz with a maximum tuning gain of 220 MHz/V.

宽调谐范围逆模门控变容管及其在2ghz压控振荡器上的应用

本文提出了一种新型的反相三端变容管，其电容范围为0.7 pF至2.3 pF，可实现a /spl + usmn/53%的电容变化。新器件采用0.35-/spl mu/m标准CMOS工艺实现。在2ghz时测量到的质量因子为22。采用这种新型变容管设计了一个2 ghz的VCO，能够实现320 MHz的调谐范围，最大调谐增益为220 MHz/V。
