description Techniques are disclosed to accurately measure the integration or accumulation of charge measured by photosite readout circuitry due to a photodiode generated current, which is generated by a photodiode as a result of impinging light reflected onto the photodiode that forms part of an imaging sensor. The techniques described herein address shortcomings of photosite operation by using a series of sequential switching states that function to maintain the charge accumulated during idle sampling times between active detection windows.
