Abstract: A pixel cell includes a photodiode to accumulate image charge. A global shutter transistor is coupled to the photodiode to reset the image charge in the photodiode in response to a global shutter control signal. A global shutter control signal generator circuit generates the global shutter control signal to have a first value signal or a second value signal. The first value signal is coupled to turn on the global shutter transistor to reset the photodiode. The second value signal controls the global shutter transistor to be in a low leakage off mode. A supply circuit is coupled to provide the second value signal to the global shutter control signal generator circuit. The supply circuit includes a variable filter circuit coupled to an output of the supply circuit to selectively vary a bandwidth of the second value signal in response to a bandwidth select signal.

Abstract: A pixel cell includes a photodiode disposed in a semiconductor material to accumulate image charge in response to light. A global shutter transistor is disposed in the semiconductor material and is selectively resets the image charge in the photodiode in response to a global shutter control signal. A global shutter control signal generator circuit is coupled to generate the global shutter control signal to have a first value, a second value, and a third value. The first value of the global shutter control signal is coupled to turn on the global shutter transistor to reset the photodiode. The third value of the global shutter control signal is coupled to control the global shutter transistor to be in a low leakage off mode. The second value of the global shutter control signal is between the first and third values and is turns off the global shutter transistor.
