This negative feedback adds frequency stability. Finally, R F and C 5 divert the input audio or video to the oscillator, not to ground. R F and C 5 are approximately 15W and 20 pF, respectively, and ...

Oscillator schematics which used single transistor circuit is proposed and design based on negative resistance concept. Symbolic input and output impedance of the propose schematic are derived.

In this paper, we present a 90-GHz CMOS voltage-controlled oscillator (VCO) that operates from 82.2 to 89.3 GHz. The proposed VCO utilizes a device-centric method to achieve a high-efficiency ...
