Power Gating
Power gating is a technique used in integrated circuits to reduce power consumption by shutting off power to a portion of the circuit when it is not in use. This is achieved by inserting a switch between the power supply and the circuit block, which can be turned on or off as needed. Power gating is particularly useful in low-power designs, such as those used in mobile devices, where battery life is a critical factor. It can also be used to reduce the heat generated by a circuit, which can improve its reliability and lifespan. However, power gating can also introduce additional design complexity and may require additional testing to ensure that the circuit operates correctly when power is restored.
