Peak Detector Circuit Captures 200-ns Pulses

With speed and low droop—other performance enhancement feasible Key is FET-input op amp fabricated on complementary-bipolar process

The classic peak-detector architecture achieves high speed with the Analog Devices AD847 and FET-input AD843 op amps, fabricated on ADI's complementary-bipolar (CB) process (Analog Dialogue 22-2). Both settle fast and stably , with high slew-rate and wide bandwidth—critical for acquiring fast peaks. Read full article
