Abstract

In this paper the design and test of a monolithic VCO implemented in a 0.25 mum SiGe technology is presented. The oscillator frequency is changing from 12 till 16 GHz when the control voltage changes from 0 to 2 V. The output power is -10 dBm @ 50 Omega. The total power consumption is 40 mW but 70% is to supply the output buffer amplifier. The predicted VCO phase noise, on the 12 GHz to 16 GHz frequency range is changing from -103 dBc/Hz to -82 dBc/Hz at an offset frequency of 1 MHz.
