Abstract
In this paper, 64 pixels pulse frequency modulation (PFM) capacitive transimpedence amplifier (CTIA) readout integrated circuit (ROIC) for quantum effect photodetector is designed. The ROIC designed with 0.35 μm 2P4M technology achieves 1.24 Ge- large charge handling with 50 fF small integration capacitor and 64 mW power consumption by pulse frequency modulation (PFM) technique. Compared to conventional integrated circuits, it has many advantages of anti-saturation, over 120 dB dynamic range (DR) realized by 10-bit counter, and can sense an input current range from few pA to few μA.
