Abstract
A 65-nm energy-ef ficient power management with
frequency-based control (FBC) is p roposed to achieve the near-op-
timum dynamic voltage scaling (DV S) in a system-on-chip system.
Since DVS and dynamic frequenc y scaling (DFS) operations are
demanded for system processor, control loop of the proposed
single-inductor dual-output (SIDO) power module is merged with
the frequency-controlled phase-locked loop (PLL) to constitute
the operation of hybrid control loop. This means that both DVS
and DFS op
