ABSTRACT:
A current switch receives a differential voltage. The differential voltage has one of first and second polarities. The current switch provides an output current at a first output if the differential voltage has the first polarity and provides the output current at a second output if the differential voltage has the second polarity. An input stage receives the differential voltage. First and second switches are coupled to the input stage, and a resistor is coupled between the first and second switches. A voltage differential is maintained across the resistor, which induces a current in the resistor. The first switch provides the current to the first output responsive to the differential voltage having the first polarity and the second switch provides the current to the second output responsive to the differential voltage having the second polarity.
