Low power consuming BiCMOS single-ended VCO for wireless LAN at C-band

Abstract

A low power consuming voltage controlled oscillator (VCO) at C-band frequencies is presented in this paper. With a supply voltage of 1.2 V and a current consumption of 1.8 mA, an output power of -3.5 dBm, an efficiency of 15 % and a phase noise of -110 dBc/Hz are achieved. Varying the tuning voltage horn 0 V to the supply voltage results in a tuning range of 400 MHz with a center frequency of 4.8 G H z With a tuning voltage from -0.5 to 5 V a tuning range of 1.1 GHz is possible. The fully integrated circuit is fabricated on a commercial 0.25 pm BiCMOS technology.
