【摘要】 读出电路是焦平面器件的重要组成部分,在与探测器互连之前对读出电路进行测试和筛选以确保焦平面的优异性能。介绍了HL064读出电路的简要原理、工作方式及其驱动脉冲。将读出电路芯片用硅铝丝键压连接入28脚双列直插式管壳中,用PI-4000系列测试系统对其进行了测试,得出其工作频率在1.25MHz以下,读出噪声为10-4V数量级,在100K?输出负载条件下,积分时间要求大于56μs。更多还原

【Abstract】 Readout integrated circuit (ROIC) is one of the key components of focal planearray (FPA), so it is necessary to measure and select ROIC before being bonded to detector.The paper introduces the working principle and modes of the HL064 ROIC, including itsdriving signal. With the PI-4000 series testing system, this chip which connected to a28-pin package by silicon-aluminium wires was measured. Results show that the workfrequency of this chip should be lower than 1.25MHz, readout noise is about the order ofmagnitude of 10-4 V, and integration time should be longer than 56μs with 100K? load.更多还原
