1. An image sensor comprising:
an image sensor pixel array having an image sensor pixel;
an amplifier having a first input terminal coupled to the image sensor pixel via a pixel readout path and having a second input terminal;
a first reference voltage terminal providing a first reference voltage to the second input terminal via a given node of the second input terminal;
a second reference voltage terminal providing a second reference voltage to the second input terminal via the given node of the second input terminal;
a first transistor coupled to the pixel readout path; and
a second transistor coupled to the pixel readout path.
