  • Abstract
    In this paper a novel bias scheme for Class-C oscillators is presented. As a proof of concept, an integrated voltage-controlled oscillator (VCO) with a 1.82-2.65 GHz tuning range is designed in a 0.18 μm CMOS technology. The VCO current consumption is 5.5 mA from a single 0.9 V power supply and achieves a low phase noise throughout the frequency range. The simulated phase noise at 1 MHz offset from the carrier frequency of 2.2 GHz is -126 dBc/Hz.
