| 摘 要： | 线列红外焦平面读出电路在正常工作时需要提供多路数字脉冲和多路直流偏置电压。本文基于0.5 μm CMOS工艺设计了一款驱动电路芯片，为电容负反馈放大型（CTIA）读出电路（ROIC）提供驱动信号。电路芯片采用带隙基准电路产生低噪声低温漂的直流偏置电压，采用数字逻辑电路生成CLK1，CLK2，RESET等八路数字脉冲。仿真及测试结果表明：驱动电路芯片输出的数字脉冲及偏置电压符合设计值，可驱动CTIA型线列红外焦平面读出电路稳定工作。

| Abstract: | Readout integrated circuit (ROIC) of linear infrared focal plane array (FPA) with capacitive trans-impedance amplifier (CTIA) should be applied with clock pulses and DC bias voltage.In this paper,a method of designing clock pulses and DC voltage for linear infrared FPA CTIA ROIC is presented.The DC voltage (about 2.6 V) is generated by bandgap reference circuit,and the eight clock pulses (CLK1,CLK2,RESET,SH1N,SH1P,SH2N,SH2P and ST) are generated by a digital logic circuit with two input signals (CLK and LSYNC).Simulation and test results show that this driving circuit can drive FPA steadily. |
