Abstract

A very fast transimpedance amplifier with a novel active feedback topology has been designed in 1.2 μm CMOS technology. The peaking time is less than 8 ns and the circuit recovers to the quiescent state in 20 ns. It exhibits high linearity over a wide input range with a gain of 3.2 mV/fC. With a silicon area of 0.05 mm² and a small power consumption of 1.5 mW at a power supply of ±2 V, it is a perfect solution for multichannel ICs used in readout systems. Typical applications include imaging systems, particle detection and solid state detector interfacing where very high counting rate is encountered
