Uncooled infrared detector readout monolithic integrated circuit with individual pixel signal processing.

摘要

A monolithic infrared detector readout circuit for a capacitive detection element (CDET) wherein a high gain preamplifier (M1, M2) is biased by a large amplifier feedback resistance (D1), on the order of 10<1><2> ohms. The output of the preamplifier is bandlimited by a low pass single-pole filter (D2, M4) having a high value resistor on the order of 10<9> ohms and then is buffered (M5, M6) prior to being multiplexed by row address signals. The output from the multiplexer switch (M7) is then applied to the column line for output to a video circuit or the like.
