Readout Circuit for Uncooled Pyroelectric IRFPA

Abstract:

Article Preview

A 320×240 readout circuit (ROIC) for the uncooled pyroelectric infrared detector was fabricated in the double-poly-double-metal (DPDM) N-well CMOS technology. Composed of X- and Y-shift register, column amplifier and correlated double sampling (CDS) circuit, the readout circuit integrated signal from the detector for frame time. It has the pitch of 50um and power dissipation of less than 50 mW. The circuit configuration, operation and testing result are described. Testing result indicates that the designed circuit meets with the requirement. Thermal images were obtained by the hybrid-integrated sensing array.
