A pyroeleoctric polymer infra red sensor array with a charge amplifier readout

摘要

This paper presents a new pixel architecture for an infra red sensor array based on a pyroelectric polymer. The pyroelectric polymer sensor is integrated with the CMOS charge amplifier. The fill factor of the sensor is optimised by placing the amplifier structure directly behow the sensing area. The maximum responsivity is 240 V/W and the specific detectivity is of the order of 10~6 cm./Hz/W.
