1. An integrated circuit (IC) device, comprising:
a functional circuit electrically coupled to a first power supply node, and operable by a first power supply voltage on the first power supply node; and
a power control circuit comprising a first transistor of a first type, and a second transistor of a second type different from the first type,
wherein
the first transistor comprises:
a gate terminal configured to receive a control signal,
a first terminal electrically coupled to the first power supply node, and
a second terminal electrically coupled to a second power supply node,
the second transistor comprises:
a gate terminal configured to receive the control signal, and
first and second terminals configured to receive a predetermined voltage, and
the first transistor is configured to, in response to the control signal, connect or disconnect the first and second power supply nodes to provide or cutoff power supply to the functional circuit.
