Abstract:
A power controlling integrated circuit cell is provided within an integrated circuit power grid to selectively couple an unswitched power supply input to a switched power supply output. The power controlling integrated circuit cell also includes a power control signal input and a power control signal output for supporting the distribution through the integrated circuit of the power control signal. The power controlling integrated circuit cell has a power switching circuit responsive to a power control input signal received at the power control signal input to selectively connect the switched power supply output to the unswitched power supply input, and a power control signal buffer circuit responsive to the switched power supply output to drive a power control output signal from the power control signal output.
