Power Management Using Duty Cycles

An integrated circuit (IC) is disclosed herein for power management using duty cycles. In an example aspect, the integrated circuit includes multiple power domains, each of which includes a respective power state controller. The power state controller acts as a bridge between global supply lines of the integrated circuit and local supply lines of the respective power domain. Global supply lines can include a first global power rail, a second global power rail, and a global clock tree. Local supply lines can include a local power rail and a local clock tree. In operation, a power state controller adjusts a power state of the respective power domain in accordance with a duty cycle. A timeslot corresponding to the duty cycle can be separated into multiple time periods with durations of the time periods being based on the duty cycle.
