摘要
介绍一种高阻红外探测器信号读出新方法——积分开关读出法;其噪声等效功率比通常的阻抗变换放大器(TIA)降低一半以上,并免除了与TIA高阻值反馈电阻有关的一系列问题.
A new method for readout of the signals from the infrared detectors with high impedance is introduced. The NEP can be reduced to less than half of that in the usual readout electronics of TIA (Trans-Impedance-Amplifier). It also frees the signal readout from some troubles due to the high resistance in TIA.
