Abstract--In this paper, a novel low-power design technique
is proposed to minimize the standby leakage power in nanoscale
CMOS very large scale integration (VLSI) systems by generat-
ing the adaptive optimal reverse body-bias voltage. The adap-
tive optimal body-bias voltage is generated from the proposed
leakage monitoring circuit, which compares the subthreshold cur-
rent (ISUB) and the band-to-band tunneling (BTBT) current
(IBTBT). The proposed circuit was simulated in HSPICE using
32-nm bulk CMOS technology and evaluated using ISCAS85
benchmark circuits at different operating temperatures (ranging
from 25
C to 100
C). Analysis of the results shows a maximum of
551 and 1491 times leakage power reduction at 25
C and 100
C,
