Abstract
A circuit for doubling the frequency of an input signal. The circuit includes a full-wave rectifier that rectifies the input signal to generate an output signal with double the frequency of the input signal. The output signal is compared to a predetermined voltage. Based on this comparison, a control signal is fed back to the full-wave rectifier and the output of the rectifier is adjusted to a predetermined level. In this manner the frequency of the input signal is doubled, and the output power is maintained constant, independent of the input power level.
