Abstract
corners. A regulation scheme with a native device
is also proposed to achieve a double regulation of supply
variation. The whole circuit is formed in a single branch
that is operated using only leakage current. The reference
generator fabricated in three (SS, TT, and FF) wafers of
a 0.18- μm CMOS. With an active area of 0.0045 mm
2,
it consumes 192 pW at room temperature. The measurement
from 45 chips (15 chips per wafer) shows untrimmed PVT
variations of 0.53%, 0.020%/V , and 33 ppm/ ◦C, respec
