This TMOS VCO operates in push-pull to produce 4 Wot 70 MHz. It consists of two MFE930 TMOS devices in a balanced VCO that generally provide better linearity than the single-ended types. Varactors are not used because the design takes advantage of the large change in Miller capacitance, G?ss, that is available in TMOS gate structures.

In the balanced VCO, the fundamental (/0 ) and/or twice the fundamental (2/0 ) can be coupled from the circuit at separate nodes.
