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

reportActive / Technical Report | Accession Number: ADA173714 | Open PDF

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 frequencyvoltage relationship found in many VCOs. This linearizer uses the forward biased voltagecurrent characteristic of a p-n junction to provide exponential linearization in a simple, thermally-stable, wide band circuit.
