Abstract

We have designed a voltage controlled oscillator (VCO) with a differential architecture containing two active inductance cells. This compact circuit (˜60??75 μm²) was realized in a 0.25 μm MOSFET technology. The oscillator can operate on a wide frequency band from 1.5 GHz up to 2.8 GHz adjustable by a tuning voltage between 0.6 V and 1.2 V. This oscillator has a static consumption of 13 mW (VCO core only) under 2.5 V supply voltage and presents a phase noise of -93 dBc/Hz @ 1 MHz.
