Abstract
A calibration circuit for calibrating a peak detector configured to detect a signal peak amplitude of an oscillator, including: a calibration oscillator configured to be supplied by at least two different supply voltages to generate respective calibration signals; a calibration peak detector configured to detect a calibration signal peak amplitude of each of the calibration signals; and a logic circuit configured to calibrate the peak detector based on the detected calibration signal peak amplitudes.
