The diode detector only requires the use of a few low cost components. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator.whiteboard. If i can create an envelope detector in excel that would be awesome. Why we could lower the ripple during pfm/pwm auto switching?
The envelope detector responds to the magnitude of the resultant carrier.
Low pass filters are often defined by insertion loss in the passband, cutoff frequency and slope. Using a slow average detector for the after settled loop, would make errors in this fast loop only present during transitional settling. The envelope is a low frequency signal compared to the.
