Abstract:
1. A system comprising: a first and second input stage to respectively receive a first input signal and a second input signal, each stage having an input terminal, a current source connection and an output terminal; the first and second input stages each including a first circuit and second circuit, the first and second circuits in the first input stage being coupled with the input terminal, output terminal and current source connection of the first input stage, the first and second circuits in the second input stage being coupled with the input terminal, output terminal and current source connection of the second input stage, wherein the second circuit of the first input stage is operative to selectively disconnect from the output terminal of the first input stage and connect to the output terminal of the second input stage, and wherein the second circuit of the first input stage is operative to selectively disconnect from the input terminal of the first input stage and connect to the input terminal of the second input stage; an output stage to sample and hold a signal corresponding to a level of a signal on one of the outputs terminals.
