Abstract
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.
