Design of 1 280×1 024 DI Multi-Functional IRFPA Readout Circuit
To meet the needs of the third generation infrared detector, a design of 1 280×1 024 pixel infrared readout circuit with large array and low power consumption is proposed. Based on the analysis of each module, low-power readout and working sequence of super array pixel unit are mainly de...
