SENSORY ARRAY WITH NON-CORRELATED DOUBLE SAMPLING RANDOM ACCESS-RESET PIXEL AND MULTI-CHANNEL READOUT

摘要

Integration of high-fidelity readout and compressive readout channels in a signal sensor array system is provided. A high-fidelity representation of the sensor array is recovered by combining the data from both the high-resolution and compressive readout channels. The signal sensory array system uses a non-correlated-double-sampling (non-CDS) pixel block readout, random-access-reset pixel, ADC-integrated image compression, high-resolution successive-approximation-register (SAR) analog-to-digital-converters (ADC), SAR ADC self-calibration, and low-noise time-domain comparator.

1. A system, comprising:
a first readout channel comprising a first resolution level analog-to-digital converter and a first resolution level multiplexer, wherein a first performance metric of the first readout channel satisfies a threshold level; a second readout channel comprising a second resolution level analog-to-digital converter and a second resolution level multiplexer, wherein a second performance metric of the second readout channel does not satisfy the threshold level; and a sensory array comprising a first set of sensors associated with the first readout channel and a second set of sensors associated with the second readout channel.
