A 70GHz VCO with 8GHz Tuning Range in 0.13um CMOS Technology

A 70 GHz VCO with 8 GHz tuning range is implemented on 0.13um CMOS. It has an output power of - 4 dBm and a phase noise of -107 dBc/Hz at 10 MHz carrier offset. From 0 to 70 degree Celsius the output power varies from -4 dBm to -8 dBm and exhibits a maximum frequency deviation of 200 MHz over this r...

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