ABSTRACT:
An integrated circuit cast on a single die having a plurality of receivers in a receiver region, a plurality of transmitters in a transmitter region, and a spatial separation region having a plurality of n-type and p-type subregions disposed on the single die to separate the transmitter region from the receiver region. The pn-junctions between the n-type and p-type subregions are reverse-biased thereby reducing or eliminating coupling of noise and crosstalk between the transmitter and receiver is reduced.
