  • Abstract
    A VCO uses coupled switched inductors to achieve a 61.9% tuning range centered at 11.75 GHz. The phase noise is measured to be -83 and -106 dBc/Hz at 100 kHz and 1 MHz offsets respectively. This 0.076 mm2 VCO is fabricated in a 90 nm standard digital CMOS process, uses 33% more area than a single-inductor VCO and consumes 7.7 mW from a 1.2 V supply.
