ABSTRACT:
A data receiver having a transfer function that exhibits peaking at high frequencies is provided to compensate an input signal provided on a transmission channel having a low pass transfer function. The data receiver includes first and second differential input terminals, which receive the differential input signal from the transmission channel. The first differential input terminal is coupled to the source of a first common gate transistor in a first self-biased common gate amplifier. The second differential input terminal is coupled to the source of a second common gate transistor in a second self-biased common gate amplifier. A differential output signal is provided from the drain terminals of the first and second common gate transistors. The first and second differential input terminals are not directly connected to any transistor gates in the data receiver, thereby enabling these differential input terminals to be safely connected directly to the transmission channel.
