摘　　要：给出了一种 1× 12 8热释电红外焦平面阵列CMOS读出电路的设计方案和焦平面的仿真及实验结果。并提出一种读出电路新方案。在此方案中 ,用电流模模拟信号处理技术由硬件实现片内CMOS电压差分器的功能 。A CMOS ROIC structure for uncooled pyroelectric IR FPA is presented, and simulative and experimental results are gived in this paper. In addition, a new ROIC structure is proposed in which with the CMOS current-mode technique for analogue signal processing, a voltage differential function is achived on chip. This will increase S/N and response speed of the system.
