Abstract
The present disclosure describes aspects of power regulation with charge pumps. In some aspects, an integrated circuit (IC) includes multiple processor cores and a power input connected to an internal power rail of the IC. The IC may also comprise embedded charge pumps coupled between the internal power rail of the IC and respective input power rails of the multiple processor cores. Capacitors of the embedded charge pumps may be implemented with on-die capacitors suitable for integration with a die of the circuit to facilitate the embedding of the charge pumps. Alternately or additionally, separate input power rails of the processor cores and the embedded charge pumps may enable more-efficient power regulation or power management on a per-processor core basis, such as when a processor core is throttled or idled to reduce power consumption.
