Abstract
A system on chip (SOC) includes a power distribution network (PDN) that has two different types of power multiplexers. The first power multiplexer type includes a lower resistance switching logic, and the second type includes a higher resistance switching logic as well as digital logic to provide an enable signal to the first type of power multiplexer. A given first-type power multiplexer may have multiple power multiplexers of the second type in a loop, the loop including communication paths for the enable signal and feeding the enable signal back to an enable input of the first-type power multiplexer.
