Abstract
An improved CMOS signal magnitude detector (SMD) for accurately quantifying the peak-to-peak magnitude of a received signal is disclosed. The SMD includes a precision gain amplifier, positive and negative peak detectors and a switched capacitive amplifier. The recited components are coupled to form a combination circuit arrangement which receives a differential signal and outputs a single ended signal which is compared with a reference signal to provide a control signal when the differential signal is of a sufficient peak to peak voltage magnitude. The control signal may be used to gate the differential signal and generate an output signal representative of received data.
