A regenerative selective logarithmic detector amplifier (LDA) can have integrated FM demodulation capabilities. It can receive a wired or wireless FM modulated signal and amplify or demodulate it with high sensitivity, high skirt ratio and minimized noise when compared to the prior art. When used in conjunction with other circuits such as a PLL or mixer, it can improve interference rejection and frequency selectivity and be locked on a precise channel in frequency and phase. The LDA produces intermittent oscillations that are self-quenched when reaching a given threshold. It also embeds the circuitry to perform direct FM discrimination. FM demodulation process is completed by a simple analog or digital frequency to voltage converter. This plus the fact that the instantaneous regeneration gain is low-medium permit to detect signals of small amplitudes buried in the noise.

A receiver includes: equalizer circuitry; clock and data recovery (CDR) circuitry; sampler circuitry; adaptation circuitry; and clock adjustment circuitry. The receiver is configured to: receive data via a channel; perform equalization operations on received data, the equalization operations resulting in equalization results; perform sampling operations responsive to the equalization results, the sampling operations resulting in data samples and error samples; perform adaptation operations responsive to the data samples and the error samples, the adaptation operations resulting in a clock adjustment control signal; and adjust a sampling clock signal relative to a CDR clock signal responsive to the clock adjustment control signal.
