Abstract
A technique for attenuating common mode transient events uses a differential receiver circuit including a band-stop filter having a stopband faround a notch frequency fof a received signal. The differential receiver circuit includes a first high-pass filter coupled in series with the band-stop filter. The notch frequency fis less than a carrier frequency fof a signal received by the differential receiver circuit. The band-stop filter may include a buffer circuit and a notch filter coupled in series with the buffer circuit. The notch filter may have a second stopband around the notch frequency f. The differential receiver circuit may have a propagation delay that is independent of a pulse width of common mode transient energy attenuated by the differential receiver circuit.
