Abstract
A peak detector for measuring the voltage amplitude of low amplitude balanced digital signals. The N-diode peak detector uses the non-linear characteristics of a diode to convert a high speed low amplitude input signal into a DC voltage, linearly proportional to the signal amplitude (peak). A compensation circuit is designed to match the characteristics of a digital modulation signal and track over a large range of temperatures and signal amplitudes. The circuit can be used for digital and analog modulation signals. For analog signals, the peak detector uses a larger number of diodes or a reduced range.
