Based on 0. 18 μm CMOS technology

a compact array-level readout circuit is designed for single photon detector. By means of quadratic correlation double sampling（ CDS） technique

the fixed pattern noise in pixel cells and readout circuit is effectively eliminated. The simulation results shows that the linear output voltage range of the readout circuit is up to 2. 8 V under the supply voltage of 3. 3 V

and the signal readout time is 80 ns

showing advantages of small occupying area

low production cost and fast readout speed. In addition

an ARMbased analog image acquisition and display system is designed and realized. The test results show that the display system can successfully restore the input analog image signals.
