Abstract

Aspects of the disclosure provide a circuit for peak voltage detection. The circuit includes a diode-based peak detector and a compensation circuit. The diode-based peak detector has a first diode, and is configured to receive a signal for peak voltage detection and generate a first voltage of a stable level indicative of a peak voltage of the signal based on the first diode. The compensation circuit has a second diode. The compensation circuit is configured to receive the first voltage and generate a second voltage of a stable level that is independent of the first diode.
