Abstract
A reduced-stage feedback-based envelope detector includes, for example, an input rectifier for rectifying a received modulated input signal and an amplifier for receiving the rectified modulated input signal at an input node. The amplifier compares the rectified modulated input signal with a reference signal, filters the rectified modulated input signal at the input node, and generates an envelope detection signal in response to the comparison and the filtering of the rectified modulated input signal. In an embodiment, the gain of the amplifier is independently determined from the bandwidth of the amplifier.
