Detector control and data acquisition with custom application specific integrated circuit (ASIC)

An application-specific integrated circuit (ASIC), the ASIC comprising:

• a plurality of preamplifiers configured to receive and amplify analog signals from a read-out integrated circuit (ROIC) of a detector, the analog signals comprising data pertaining to infrared or near-infrared photons detected by diodes of the detector;
• a plurality of analog-to-digital converters (ADCs) configured to convert the amplified analog signals from the plurality of preamplifiers to digital signals;
• and
• a plurality of math blocks configured to perform configurable processing of the digital signals from the plurality of ADCs to process the data pertaining to the infrared or near-infrared photons, and
• wherein the ASIC includes a sequencer and a CMOS, the CMOS located proximate to the detector as compared to the processing circuitry and providing a reference voltage.
