100 GHz push-push oscillator in 90 nm CMOS technology

A 100 GHz fixed-tuned oscillator was designed and fabricated using a 90 nm bulk CMOS process. Push-push mode was chosen to improve the power output. The oscillator exhibits -3 dBm output power at 101 GHz with 27 mW power consumption. The measured SSB phase noise is -85 dBc/Hz at 1 MHz offset Resonators are implemented with transmission lines to avoid the need of high quality capacitors and inductors.
