A 170-dB \Omega CMOS TIA With 52-pA Input-Referred Noise and 1-MHz Bandwidth for Very Low Current Sensing

A fully integrated current sensing interface chip employing a capacitive-feedback transimpedance amplifier (TIA) is presented. A robust dc current removal block is proposed to prevent the dc portion of the input current from saturating the output voltage. This block allows the TIA to operate in the...
