Abstract

By exploiting the intrinsic multiple oscillation modes of LC resonator with cross-coupled transistor pair, a differential VCO is designed for multi-standard RF transceivers. The series resistance introduced by transistor switches has been omitted to improve the quality factor of resonator. It operates at the high-frequency series-resonant and low-frequency parallel-resonant mode via varactor switching bias. Both frequencies are not harmonically related. Accumulation-mode MOS varactor tuning changes the net impedance of LC-tank to shift the oscillations from one resonance mode to anothe
