摘要： An integrator having an offset evaluation circuit and a collected charge reduction circuitry and method for using the integrator. The integrator includes an amplifier, operable to amplify an input signal, an integration capacitor for collecting charge indicative of a level of the input signal and an offset capacitor. The offset evaluation circuit is operable to charge the offset capacitor with charge corresponding to an offset voltage of the amplifier and the collected charge reduction circuitry is operable to collect charge resulting from disconnection of the offset evaluation circuit, thereby reducing an amount of charge and associated noise input to the amplifier.

摘要： Systems and methods for imaging in the short wave infrared (SWIR), photodetectors with low dark current and associated circuits for reducing dark currents and methods for generating image information based on data of a photodetector array. A SWIR imaging system may include a pulsed illumination source operative to emit radiation pulses in the SWIR band towards a target resulting in reflected radiation from the target; (b) an imaging receiver including a plurality of Ge PDs operative to detect the reflected SWIR radiation and a controller, operative to control activation of the receiver for an integration time during which the accumulated dark current noise does not exceed the time independent readout noise.

摘要： Light detecting structures comprising germanium (Ge) photodiodes formed in a device layer of a germanium on-insulator (GeOI) wafer, focal planes arrays based on such Ge photodiodes (PDs) and methods for fabricating such Ge photodiodes and focal plane arrays (FPAs). An FPA includes a Ge-on-GeOI PD array bonded to a ROIC where the handle layer of the GeOI layer is removed. The GeOI insulator properties and thickness can be designed to improve light coupling into the PDs.
