Design of a low-power 2.4GHz current reuse VCO for biomedical implantable applications

Abstract

In this paper we present the design of LC voltage control oscillator (VCO) operating at 2.4GHz in 130nm CMOS technology using the current reuse topology, achieving a Phase Noise of -118dBc/Hz @ 1MHz with a turning range from 2.52GHz to 2.23GHz, control voltage from 0V to 1.2V while dissipating 232.4μW at resonance with 1.2V supply voltage.
