description A buffered direct injection pixel can be operated such that it is automatically zeroed. The operation includes: during a normal operating mode, controlling a gate voltage of an injection transistor with the output of an amplifier to control a bias of photo-current source, an inverting input of the amplifier being connected to input of the injection transistor through a nulling capacitor; during a nulling operation, closing a first switch to connect the nulling capacitor directly to an output of the amplifier; during the nulling operation, closing a second switch to directly couple the input of the injection transistor to a bias voltage causing the nulling capacitor to store a difference between an output of the amplifier and the bias voltage; and after the nulling operation, providing the voltage stored on the nulling capacitor to the inverting input by opening the first and second switches.
