Abstract
In an integrated circuit including a clock gating cell based on a set-reset (SR) latch, the clock gating cell includes a first 2-input logic gate configured to receive a clock input and a first signal, and generate a second signal, a first inverter configured to receive the second signal, and generate a clock output, and a 4-input logic gate including a 4-input keeping logic gate configured to generate the SR latch by being cross-coupled to the first 2-input logic gate and keep a level of the first signal.
