Abstract
A circular translates an input signal about an input reference voltage to an output signal referenced to a different voltage. The input signal may be scaled, and multiple inputs may be scaled independently and summed. Shift networks transfer the input signal across a resistor on the input of a current mirror; the output signal appears across a resistor in an output of the mirror.
