Some embodiments relate to an imaging system including an active pixel a comparator, a write control circuit, and an analog-to-digital conversion (ADC) memory. The active pixel may include a photodiode and a plurality of transistors. The comparator may be operative coupled to the active pixel and configured to receive an output of the active pixel. The write control circuit may be operative coupled to the comparator and configured to receive an output from the comparator. The ADC memory may be operatively coupled to the write control circuit. A data structure may be stored in the ADC memory, and may be configured to store at least a first data string, which may include a set of flag bits for identifying each ADC operation performed and a set of ADC data bits.

System, method, device and data structure for digital pixel sensors

Some embodiments relate to an imaging system including an active pixel and an analog-to-digital conversion (ADC) circuit including comparator. The comparator may be operatively coupled to the active pixel and configured to receive an output of the active pixel. The back-end ADC and memory circuit may be operatively coupled to the active pixel. The back-end ADC and memory circuit may include a write control circuit, an ADC memory operatively coupled to a read/write data bus and to the write control circuit, and a state latch operatively coupled to the write control circuit.

A power supply apparatus supplies a power supply voltage V. The power supply apparatus includes a compensation circuit in addition to a main power supply. The compensation circuit receives, via its input, as a feedback signal, a detection signal Vthat corresponds to the power supply voltage V. The compensation circuit has input/output characteristics fthat correspond to the characteristics of the main power supply and the characteristics of a target power supply to be emulated. The compensation circuit injects or otherwise draws a compensation current ithat corresponds to the detection signal Vto or otherwise from a node for generating the power supply voltage V.
