Abstract

A 2.4-GHz CMOS VCO is presented employing pMOS transistors as voltage-controlled capacitances and on-chip hollow spiral inductors. The design was implemented in a standard digital 0.8μm CMOS process and exhibits a 15% tuning range at 2.5 V supply voltage and 9 mA supply current. Phase-noise measurements show a phase-noise of about −118 dBc/Hz at 1 MHz from the carrier.
