Add Programmable Gain To a Peak
Detector : 10/14/02
Electronic Design - Ideas for Design / If your
system's signal processing requirements in-clude
peak detection and amplification, consider a simple
circuit that will satisfy both needs and save
hardware. The single-supply circuit shown in the ...

Droopless Operation:
05/15/00 Electronic Design - Ideas for Design / Most
peak detectors employ a rectifier and a sample-andhold
circuit, which is prone to output droop. In an
alternative approach, shown in the figure, a 5-bit
digital potentiometer with servo loop is used to. .

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..
