Abstract

A design of front-end preamplifier for measurement of optical response of photo-detector registering light produced by semiconductor scintillator is presented. The designed preamplifier is based on a current mode, regulated cascode (RGC) structure. A comparison with a previously reported common gate (CG) structure is provided. The experimental prototype was designed in 0.5μm CMOS process. With a 5 V power supply, total power consumption of a chip is 7.5mW. With 50 pF input capacitance and 100 nA leakage current of interfaced photo-detector, the equivalent noise charge (ENC) is 8000.
