Abstract
A receiving apparatus includes a terminating network for a three-wire serial bus and a feedback circuit. Each wire of the three-wire serial bus may be coupled through a resistance to a common node of the terminating network. The feedback circuit has a first amplifier circuit having an input coupled to the common node, a comparator that receives an output of the first amplifier circuit as a first input and a reference voltage as a second input, and a second amplifier circuit responsive to an output of the comparator and configured to inject a current through the common node.
