A RISC-V Processor SoC With Integrated Power Management at Submicrosecond Timescales in 28 nm FD-SOI.

This paper presents a RISC-V system-on-chip (SoC) with integrated voltage regulation, adaptive clocking, and power management implemented in a 28 nm fully depleted silicon-on-insulator process. A fully integrated simultaneous-switching switched-capacitor DC-DC converter supplies an application core using a clock from a free-running adaptive clock generator, achieving high system conversion efficie...
