Abstract:
Pixel arrangements in time-of-flight sensors are presented that include sensing elements that establish charges related to incident light, charge storage elements that accumulate integrated charges transferred from the sensing elements, and diffusion nodes configured to establish measurement voltages representative of the integrated charges that are dumped from the charge storage elements. The pixel arrangement includes analog domain output circuitry comprising a measurement capacitance element that stores the measurement voltage, and a reset capacitance element that stores a reset voltage established at the diffusion node during a reset phase performed prior to a measurement phase. The analog domain output circuitry subtracts the stored reset voltage from the stored measurement voltage for processing into a pixel output voltage that at least partially reduces readout voltage uncertainty of the pixel arrangement.

Claim (Index 1):
A pixel arrangement in a time-of-flight sensor, comprising:\n a polysilicon sensing element of a differential pixel structure configured to establish charges related to incident light during a measurement phase; a charge storage element configured to accumulate integrated charges of the measurement phase transferred from the polysilicon sensing element; a diffusion node configured to establish a measurement voltage representative of ones of the integrated charges established during the measurement phase that are dumped from the charge storage element; and analog domain output circuitry comprising a measurement capacitance element that stores the measurement voltage, and a reset capacitance element that stores a reset voltage established at the diffusion node during a reset phase performed prior to the measurement phase; the analog domain output circuitry configured to subtract the reset voltage stored in the reset capacitance element from the measurement voltage stored in the measurement capacitance element to establish a compensated result that at least partially reduces readout voltage uncertainty of the pixel arrangement, and provide the compensated result for processing into a pixel output voltage differentially derived with at least a further compensated result associated with a further polysilicon sensing element of the differential pixel structure during an associated measurement phase.
