An ultra-low noise integrated circuit for mercury cadmium telluride (HgCdTe) infrared detectors is proposed. Noise reduction techniques such as active noise cancellation are commercially successful and have been implemented using silicon-based integrated circuits to reduce background and externally-induced noise. While silicon dominates infrared sensor readout electronics, silicon-based circuits have a limited bandwidth due to low electron mobility. Compound semiconductor-based amplifiers circuits, employing transistors like the pseudomorhic high electron mobility transistors (pHEMTs), have lower noise figures than conventional silicon-based circuits. They are also faster due to the higher electron mobility and have greater efficiency.. However, circuits employing active noise cancellation have not been implemented using compound semiconductor transistors. This project involves the design, fabrication, packaging and testing of a GaAs-based low noise read-out integrated circuit for HgCdTe infrared detectors employing active noise control. The circuit will have a noise figure less than 1 dB and a bandwidth of at least 10 GHz.
