Abstract
In various embodiments, there is provided a method comprising receiving a waveform; rectifying the waveform to generate a rectified waveform; comparing the rectified waveform with a first voltage to generate a first compare signal, wherein a first edge of the first compare signal occurs at a first time when an instantaneous value of the rectified waveform becomes higher than the first voltage; comparing the rectified waveform with a second voltage to generate a second compare signal, wherein a first edge of the second compare signal occurs at a second time when the instantaneous value of the rectified waveform becomes higher than the second voltage; and based at least in part on the first time and the second time, estimating a voltage of the waveform.
