Abstract
A Compressing Capacitively Coupled Transimpedance Amplifier (CCTIA) circuit (10) has an amplifier (AMP) with a variable capacitance feedback network (C1, C2, C3, Q1, Q2) coupled between a current receiving amplifier input node and an amplifier output node. The output node outputs a voltage in response to a received current. The variable capacitance feedback network is responsive to the output voltage for establishing one of a plurality of different transimpedance values for the circuit such that the circuit exhibits a greatest transimpedance value for an input current having a magnitude below a threshold magnitude, and a lesser transimpedance value for an input current having a magnitude equal to or above the threshold magnitude.
