Abstract
There is disclosed a differential current mirror system and method for providing differential output current signals that are proportional to differential input current signals in which common mode current signals are rejected. The system comprises a pair of diode connected transistors and a differential amplifier. The pair of diode connected transistors comprises a first and second transistor coupled together. The differential amplifier comprises a third and fourth transistor coupled together in a differential amplifier configuration. The gate of the third transistor receives a first input current signal from the drain of the first transistor and the gate of the fourth transistor receives a second input current signal from the drain of the second transistor.
