This simulation illustrates a precision positive peak detector driven by a composite AC input. The upper plot shows the input waveform (blue) with multiple frequency components, resulting in sharp peaks and valleys. The measured values confirm a peak amplitude of about ±761 mV, a dominant frequency near 200 Hz, and an RMS level of roughly 447 mV. These numbers are typical for an audio-like signal rather than a pure sine wave. In the lower schematic, the op-amp is configured with very high open-l

PEAK DETECTOR: Peak detection circuit captures and holds the highest voltage level of a varying input signal. Using an op-amp, diode, and capacitor, it stores the peak value, while a buffer op-amp ensures stable output without loading the capacitor. It’s commonly used in signal processing and instrumentation. #peakdetection #opamp #diode #circuitdesign #electronicsrd #ElectronicsEducation #Electronics | Electronics Education
