1. An apparatus comprising:
a first input;
a second input;
a third input;
a control;
a circuitry to adjust logic levels of the first input, the second input, and the control in a first operation mode; and
a gate to receive the first input, the second input, and the third input, wherein the third input is coupled to an output of the gate, wherein the gate comprises:
a first capacitor having a first terminal coupled to the first input, and a second terminal coupled to a summing node;
a second capacitor having a third terminal coupled to the second input, and a fourth terminal coupled to the summing node;
a third capacitor having a fifth terminal coupled to the third input, and a sixth terminal coupled to the summing node; and
a device coupled to the summing node and a supply rail, wherein the device is controllable by the control, wherein the circuitry is to adjust a function of the gate in the first operation mode, and wherein the circuitry is to allow the gate to operate in accordance with the function in a second operation mode.
