Abstract
A monolithic infrared detector readout circuit for a capacitive detection element wherein a high gain preamplifier is biased by a large amplifier feedback resistance, on the order of 10.sup.12 ohms. The output of the preamplifier is bandlimited by a low pass single-pole filter having a high value resistor on the order of 10.sup.9 ohms and then is buffered prior to being multiplexed by row address signals. The output from the multiplexer switch is then applied to the column line for output to a video circuit or the like.
