Abstract :
Presented is a technique for implementing the functions of charge skimming and variable integration time in Schottky-barrier focal plane arrays (FPAs) that utilize a field plate. This technique requires only pulsing the field plate that lies over the diode and is currently DC biased to suppress diode edge leakage. Therefore, no additional structure is needed in the silicon substrate, and the basic readout clocking is unaffected. Any interline transfer FPA can benefit from this approach. Both qualitative theory and confirming experimental results are described.<>
