1. A calibration circuit, comprising:
a calibration signal generator configured to:
receive an oscillator signal provided by an oscillator, and
generate a calibration signal based on the oscillator signal, the calibration signal being generated to have a predetermined amplitude;
a calibration peak detector configured to detect a peak amplitude of the calibration signal; and
a logic circuit configured to calibrate a peak detector, connected to the oscillator for detecting a peak of the oscillator signal, based at least in part on the peak amplitude of the calibration signal.
