A 70GHz VCO with 8GHz tuning range is implemented on 0.13um CMOS. It has an output power of - 4dBm and a phase noise of -107dBc/Hz at 10 MHz carrier offset. From 0 to 70 degree Celsius the output power varies from -4dBm to -8dBm and exhibits a maximum frequency deviation of 200MHz over this range. The VCO has the highest figure of merit (-169.8dBc/Hz) of any VCO fabricated on bulk CMOS operating above 60GHz.
