| Abstract: | Based on the operating principle of APD(Avalanche Photodiode Diode),the characteristic of high voltage protection and integration time adjustable techniques are investigated.The cell circuit and the whole circuit of the ROIC(Readout Integrated Circuit)are designed.This circuit can achieve high-voltage protection function and the integral switch circuit can achieve precise control function,which have been verified on the small array(64×64)chips.The simulation results under 77 K show that ROIC has characteristic of high voltage protection(17 V).In active imaging mode,its integration time can be adjusted from 10 ns to 150 ns and integration time can be delayed from 10 ns to 310 ns.The maximum working frequency can be higher than 5 MHz. |
