Inexpensive Peak Detector Features Droop less Operation: 05/15/00 Electronic Design - Ideas for Design / Most peak detectors employ a rectifier and a sample-handhold circuit, which is prone to output droop.

Precision Peak Detector

Sampling peak detector has shutdown feature: 05/16/2002  EDN - Design Ideas /  You face a serious problem in using a slow ADC with a fast peak detector. The circuit in Figure 1 allows a slow ADC to measure a fast, sampled signal peak. The 100-MHz peak detector for ultrasonic-pulse sampling uses a fast MAX4231 amplifier from Maxim (www.maxim-ic.com). This amplifier has a shutdown feature that facilitates power savings without losing the sampled information.
