  • Oscillator with variable reference
    Patent number: 7098753
    Abstract: A circuit for varying an amplitude of an oscillation signal comprises an oscillator, signal processing circuitry, a first feedback circuit, and a second feedback circuit. The oscillator generates the oscillation signal and has a control input to vary the amplitude of the oscillation signal. The signal processing circuitry processes the oscillation signal. The first feedback circuit is configured to control the control input of the oscillator by comparing a reference value and an input amplitude of an input of the signal processing circuitry. The second feedback circuit generates the reference value by comparing an output amplitude of an output of the signal processing circuitry and a predetermined value.
