Techniques are disclosed relating to peak detection. In one embodiment, an apparatus is disclosed that includes an amplifier configured to amplify a signal. The apparatus further includes a peak detector DC coupled to an output of the amplifier. The peak detector includes a first comparator stage configured to perform subtraction of a threshold signal from the amplified signal. The peak detector further includes a second comparator stage is configured to amplify a differential output signal of the first comparator stage indicative of a result of the subtraction. In some embodiments, the amplifier and peak detector are included within automatic gain control system in a path for an in-phase or quadrature channel of the receiver chain.
