Abstract
A synchronous demodulation circuit uses a digitally controlled track-and-hold circuit to capture the peak amplitude of a rectified signal. A microcontroller controls the track-and-hold circuit. In particular, the microcontroller controls a hold mode of the track-and-hold circuit to capture the peak amplitude of the rectified signal.
