We present a tunable flipflop-based frequency divider and a fully differential push-push VCO designed in a 200 GHz fT SiGe BiCMOS technology. A new technique for tuning the sensitivity of the divider in the frequency range of interest is presented. The chip works from 60 GHz up to 113 GHz. The VCO is based on a new topology which allows generating differential push-push outputs. The VCO shows a tuning range larger than 7 GHz. The phase noise is 75 dBc/Hz at 100 kHz offset. The chip shows a frequency drift of 12.3 MHz/C. The fundamental signal suppression is larger than 50 dB. The output power is 2times5 dBm. At a 3.3 V supply, the circuits consume 35 mA and 65 mA, respectively.
