A buffer direct injection and direct injection readout circuit with mode selection design for infrared focal plane arrays

Research progress on digital ROIC of infrared focal plane array detector

“…ADC conversion is carried out by the chip-level digital ROIC at the last part of the analog signal transmission connection, which has high power consumption, high speed requirement, and significant noise interference [16,17]. There are currently just a few publications on infrared focal plane array detectors with medium-scale to large-scale cooling that employ chip-level digital ROIC.…”
