Simulation Design of LC VCO Based on 0.18µm CMOS Technique

Abstract

This paper introduces the way to minimize the phase noise of VCO using LC 2nd harmonic wave filtering technology, and fulfills the design of 1.8GHz low phase noise, low power consumption VCO with TSMC RF CMOS 0.18μm standard technique. The tuning range reaches 560MHz, phase noise - 121dBc/ Hz@1 MHz. The method, introduced in the paper to minimizing phase noise of VCO, puts forward a valuable reference to integrated circuit design.
