Abstract
An integrated circuit device includes an external power supply input configured to be coupled to an external power supply and a digital circuit, such as a clock signal generator circuit, that generates noise at a power supply input thereof. The device further includes a replica load circuit and a power supply circuit coupled to the external power supply input, to a power supply input of the digital circuit and to a power supply input of the replica load circuit. The power supply circuit is configured to selectively couple the external power supply node to the power supply input of the digital circuit responsive to a voltage at the power supply input of the replica load circuit. The replica load circuit may be configured to provide a load that varies responsive to a voltage at the power supply input of the digital circuit.
