Abstract

A 1.8 GHz fully integrated Voltage Controlled Oscillator (VCO) is presented. Through inductor optimization, the phase noise is as low as -127.5 dBc/Hz at 600 kHz and -142.5 dBc/Hz at 3 MHz. A 28% wide tuning range is achieved with a 1.8 V power supply. The VCO exceeds the DCS-1800 phase noise requirements with at least 4 dB over the whole DCS-1800 frequency band. The VCO is implemented in a 2-metal layer, 0.25 μm standard CMOS technology, using no external components nor additional processing steps
