Low-power readout circuit for quanta image sensors
A low-power analogue readout circuit for quanta image sensors is reported. A modified charge-transfer amplifier is used in column-parallel circuits to reduce the internal readout circuit power 50-fold compared to the state of the art, and will achieve 2 mW total power dissipation (all columns) when applied to a 1 Mpixel binary image sensor operating at 1000 fields per second.
