Readout Integrated Circuit Design for infrared detector with Dual Switched Type

摘要

This research designed a readout circuit with dual type switching for infrared sensors. The pixel readout circuit structure uses DI (direct injection) and CTIA (capacitive transimpedance amplifier). The readout circuit has four operating modes,which control single or dual band using signal control and the TSMC 0.35um 2P4M 5V process. The input current middle wavelength is set between 2nA to 4nA, the long wavelength is set between at 6nA to 8nA, the output voltage swing is 2.8V,and power consumption is 22.19mW.
