ABSTRACT:
A voltage controlled oscillator includes a varactor (201) and a transistor (202) and a ground via (203), of epitaxially grown silicon that is etched to provide respective pedestals embodying the varactor (201) and the transistor (202) and the ground via (203), an L-C resonator circuit, the varactor (201) and an inductor providing a tank circuit that changes the frequency of the L-C resonator circuit, and that shifts the average frequency of the oscillator to that of an input voltage to the collector of the transistor (202).
