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 following circuit improves upon a simple peak detector by using a high frequency op-amp and feedback circuitry. The result is better accuracy and more sensitivity at the input. To view the ...

I recently received an email from a student who needed to design a circuit to detect peaks in a 10-MHz analog signal. His plan was to use an A/D converter sampling at well beyond the Nyquist frequency ...
