Abstract
This paper presents a back-gate coupled quadrature voltage-controlled oscillator (QVCO) based on a differential Colpitts structure. With this topology, the QVCO achieved better performance on tuning range, power dissipation, and noise as compared with conventional structures of QVCO. Designed in TSMC 0.18 μm CMOS process, this QVCO showed a 33% tuning range. The simulated power dissipation is 2.89 mW with 1V supply voltage. The simulated phase noise at 1-MHz offset frequency is -108.52 dBc/Hz at 3.85 GHz center frequency.
