An image sensor capable of detecting nano-ampere transient signals with strong background illumination

PDF Version Also Available for Download.

Description

A readout detector integrated circuit (IC) has been developed which is capable of detecting nano-ampere photo-current signals of interest in a high (micro-ampere) background illumination or DC noise level (SNR=92dB). The readout detector sensor IC processes transient signals of interest from a separate photodiode array chip. Low noise signal conditioning, filtering, and signal thresholding implement smart sensor detection of only ``active pixels.`` This detector circuit can also be used to perform signal conditioning for other sensor applications that require detection of very small signals in a high background noise environment.
