超宽频带VHF频段CMOS LC VCO
An Ultra Wideband VHF CMOS LC VCO
摘要
Abstract
This paper presents a VHF CMOS VCO. The most significant improvement on the VCO is that the cross-coupled MOSFET pairs are divided into several switchable parts so the characteristics can compensate the state change that results from the frequency tuning of the oscillator. This VCO is implemented in 0.18μm CMOS with a core area of about 550μm × 700μm. The test results show that the tuning range covers 31～111MHz with a power consumption between 0.3～6.9mW and a phase noise at a 100kHz offset of about - 110dBc/Hz.关键词
