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 ...
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.
