摘要：

A VCO uses coupled switched inductors to achieve a 61.9% tuning range centered at 11.75GHz. The phase noise is measured to be -83 and -106dBc/Hz at 100kHz and 1MHz offsets respectively. This 0.076mm(2) VCO is fabricated in a 90nm standard digital CMOS process, uses 33% more area than a single-inductor VCO and consumes 7.7mW from a 1.2V supply.
