Abstract

This paper presents a new pixel architecture for an infrared sensor array based on a pyroelectric polymer integrated with a CMOS charge amplifier. The fill factor of the sensor is optimised by placing the amplifier structure directly below the sensing area. The maximum responsivity is 1000 V/W @ 1 Hz and the specific detectivity is 6.84×106 cm √Hz/W @ 100 Hz. These results are presented in comparison with those of a single MOSFET with an external 109 Ω bias resistor.
