Abstract

A current-reused voltage-controlled oscillator (CRVCO) with amplitude-balanced technique is presented. A cascode cross-coupled pair is adopted, which is used to improve the difference between the differential output amplitudes of CRVCO at a 1.3 V supply voltage. The measured amplitude imbalance ratio is less than 0.15%. The measured phase noise is −114 dBc/Hz at 1 MHz offset when oscillation frequency is at 7.8 GHz, resulting in an FOM of −187 dBc/Hz.
