The Development of a High Speed Exponential Function Generator for Linearization of Microwave Voltage Controlled Oscillators.

Abstract

Voltage Controlled Oscillators used in radar signal simulators usually employ piecewise approximation linearizers to compensate for nonlinear frequency versus voltage tuning characteristics. A linearizer was developed which closely approximates an exponential (frequency/voltage) relationship found in many VCO's. This linearizer uses the forward biased (voltage/current) characteristic of a p-n junction to provide exponential linearization in a simple, thermally-stable, wide band circuit.
