Abstract
A differential current mode amplifier device generates a common mode bias current. A translinear multiplier receives at two inputs this common mode bias current and a differential mode current to be amplified and delivers at two outputs an amplified differential mode current. The translinear multiplier is biased in a manner depending on the bias current received by the translinear multiplier. The device includes a circuit for compensating the common mode current at the output of the translinear multiplier.
