Abstract—Dynamic voltage and frequency scaling (DVFS) is an
effective way for system-level power saving. However, lowering
the supply voltage may cause some concerns including yield loss
and speed degradation. This paper presents a fully integrated
linear regulator that can dynamically assign the supply voltage of
a SRAM cell to improve the read and write margins in a DVFS
system. To minimize the timing overhead during mode transitions,
this design ado
