Abstract
A device includes a first virtual power line, a second virtual power line, a first delay circuit, and a first wakeup detector. The first virtual power line and the second virtual power line are coupled to a power supply correspondingly through a first group of transistor switches and a second group of transistor switches. The first delay circuit is coupled between gate terminals of the first group of transistor switches and gate terminals in the second group of transistor switches. The first wakeup detector is configured to generate a first trigger signal after receiving a signal from the first delay circuit.
