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.
