Abstract :
Colpitts oscillators have long been known for their excellent phase-noise properties; yet, a differential CMOS Colpitts oscillator, directly derived from a singled-ended topology, did not show a better phase noise performance than the conventional CMOS differential-pair LC-tank oscillator, not even theoretically (Andreani, 2005).
