- Abstract
A Ka-Band voltage controlled oscillator (VCO) using GaAs Heterojunction Bipolar Transistor (HBT) technology in a fully differential Colpitts configuration achieves low phase noise at a high oscillation frequency. It operates from 29.71 to 30.43 GHz and its phase noise is -110.7 dBc/Hz at 1 MHz offset at 30.07 GHz. It consumes 51 mW from a 5 V supply and occupies an area of just 0.65 mm x 0.68 mm. Its figure of merit (FOM) is -183.2 dB/Hz.
