Abstract
A voltage controlled sine wave oscillator is provided in which the frequency of the output signal is a linear function of the amplitude of an input control signal. The output signal may be of constant amplitude with changes in frequency, or its amplitude may be a linear function of its frequency. Two-phase quadrature output signals may be provided for multi-phase applications. The oscillator of the invention in the embodiment to be described herein is solid state, and it makes use of operational integrators, analog multipliers, and associated circuitry to generate the outputs.
