Abstract
An integrated circuit (IC) that operates in high and low power modes includes high and low power regulators, first and second sets of circuits, a switch connecting the high power regulator and the second set of circuits, and a wake-up control system. The wake-up control system includes a state machine that enables the high power regulator when the IC is in the high power mode, and enables the low power regulator when the IC is in the low power mode. The switch is closed when the high power regulator reaches a first threshold voltage. The state machine operates on a low frequency clock signal when the IC is in the low power mode and during wake-up, and on a high frequency clock signal in the high power mode after the switch is closed.
