Abstract

An oscillator circuit that includes a Wien bridge oscillator circuit, a full-wave rectifier circuit, coupled to an output of the Wien bridge oscillator circuit, an integrator circuit, coupled to an output of the full-wave rectifier circuit, and a multiplier circuit. The multiplier circuit may include a first input coupled to the output of the Wien bridge oscillator circuit, and a second input, coupled to an output of the integrator, wherein the multiple signals are configured to provide dynamic gain control to the Wien bridge oscillator circuit.
