基于电流镜积分的红外探测器读出电路设计
An IR ROIC Design Based on Current Mirroring Integration
摘要
Abstract
By analyzing the working principle and noise of current mirroring integration(CMl) readout circuit, a CMl structure is designed here. The CMI readout circuit is simulated and implemented using CSMC 0.5 μm CMOS integrated technology. The simulated results show that the circuit provides a maximum charge storage capacity of 6.25×107 electrons for a 2pF integration capacitance and 5 V power supply,the detector bias voltage is stable at 3.615 mV for 50 pA detector current, and the noise of the designed CMl circuit is 3. 451 nsqV/Hz for 1 kHz frequency, even more, the structure has a large linearity no less than 99% in integration and two paths of differential output circuit.关键词
