  • Description: PURPOSE: An ISI elimination differential receiver is provided to relax inter-symbol interference in a system that employs a high data transmission rate. CONSTITUTION: The ISI elimination differential receiver(2) that eliminates inter- symbol interference(ISI) caused in a differential digital signal when a long run of a digital signal(0 or 1) is transmitted through a long cable, is configured by either of the bipolar technology(npn or pnp) and the insulation gate FET technology(p-channel or n-channel). A first differential transistor(TR) pair (T1, T'1) is connected to a second differential TR pair(T2, T'2) with a weaker coupling via a filter network(R'1, C', R'2, R'1, R'3) so that a high pass 'shelf' filter transfer function is in existence between a differential input signal and an output signal. This transfer function relaxes the ISI by decreasing a gain of the long run in the digital signal (low frequency) and increasing a gain of a state transition edge (high frequency).
