ABSTRACT:
A differential current amplifier operating at a low power while maintaining high linearity includes a bridge arrangement of current mirrors connected to each input node of the amplifier, and a common mode feedback circuit. Opposite legs of the bridge are controlled commonly, but complementary to the other legs. An integrated resistor network of the current amplifier balances delay of the output current and controls amplifier bandwidth.
