ABSTRACT:
A voltage controlled oscillator amplitude control circuit has a voltage controlled oscillator circuit to output an oscillating signal having a controlled amplitude. It also has a control circuit to control the amplitude of the oscillating signal by providing a dominant pole, a filtering function, rectification, and a gain at a single node of the circuit.
