Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate an output signal oscillating at a frequency in response to a first control signal and a second control signal. The second circuit may be configured to generate the second control signal in response to (i) an input voltage and (ii) the output signal. The second circuit (i) generates the second control signal by comparing a peak voltage of the output signal to the input voltage and (ii) adjusts an amplitude of the control signal in response to the comparison.
