Ultra-responsive peak detector

Design Tip

The peak detector presented here will respond to amplitude changes of the input signal within one-half of a cycle. Because no ‘bleed’ resistor is required on the output capacitor, droop is only limited by the ‘off’ resistance of a CMOS switch. Note that circuit is more accurately described as an amplitude detector, as the output level is equal to the average of the absolute values of the positive and negative amplitudes.
