  • Abstract
    This paper describes a programmable current reference which is designed to work stably over supply voltage in 77K without external component. It is designed to be used in an IRFPA ROIC (readout IC) as a reference current source. This current reference is based on CSMC 0.5 μm standard CMOS process with supply voltage of 5V. In low-precision testing condition, measurement result of the output current varies from about 80 nA to 120 nA with the supply voltage variation from 2.8V to 6V at room temperature.
