A system and circuit for virtual power grid is disclosed. In one embodiment, a switch system for a virtual power grid includes a first transistor for connecting a power supply to a node of a virtual power grid for an isolated region of circuitry via the first transistor upon a receipt of a first control signal to turn on the first transistor. The switch system further includes a second transistor for connecting the power supply to the isolated region of circuitry via the second transistor upon a receipt of a second control signal to turn on the second transistor. In addition, the switch system includes a self-timed enable module for generating and forwarding the second control signal when a voltage level at the node of the virtual power grid which is charged by the power supply via the first transistor reaches a threshold voltage.
