A fully-monolithic SiGe differential voltage-controlled oscillator for 5 GHz wireless applications

A fully integrated and differential SiGe VCO was designed for 5 GHz wireless applications. The measured phase noise is -98 dBc/Hz at 100 kHz offset off the 5 GHz carrier. It has a tuning range of 12.3% with a control voltage from 0 to 3 V, and a figure of merit of more than -180 dBc/Hz, The current...

Description
Summary:A fully integrated and differential SiGe VCO was designed for 5 GHz wireless applications. The measured phase noise is -98 dBc/Hz at 100 kHz offset off the 5 GHz carrier. It has a tuning range of 12.3% with a control voltage from 0 to 3 V, and a figure of merit of more than -180 dBc/Hz, The current drawn from 3 V is 5 mA for the core and 2.2 mA for the output buffers.
