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 11):
The ToF imaging sensor of  claim 10 , wherein the charge storage elements each comprise a polysilicon capacitor element formed with an underlying p-type dopant well of a higher p-type doping level than the semiconductor substrate; and\n wherein biases on the charge storage elements establish a higher potential level than the bias potential of an associated bias gate element to provide the pathway for at least the portion of the charges established at the associated polysilicon sensing element to be transferred to the associated charge storage element from the associated polysilicon sensing element.
