Phase noise performances of a cross-coupled CMOS VCO with resistor tail biasing

The Voltage Controlled Oscillator (VCO) is a fundamental block in RF IC architectures. Today’s wireless communication applications do require a high level of performances from such a circuit, and specifically its phase noise figure and its power consumption. In fact, modern standards often demand for phase noise level better than - 95 dBc/Hz at 100 KHz in the vast majority of cases, with supply voltages approaching the 1 V range. This paper presents the design challenges of a cross-cou
