Minimum Energy CMOS Design with Dual Subthreshold Supply and Multiple Logic-Level Gates
"... Abstract—This paper presents a method for minimum energy digital CMOS circuit design using dual subthreshold supply voltages. Stringent energy budget and moderate speed requirements of some ultra low power systems may not be best satisfied just by scaling a single supply voltage. Optimized circuits ..."

Using Dual Sub-Threshold Supply Voltages
"... Power dissipation in high performance systems requires more expensive packaging. In this situation, low power VLSI design has assumed great importance as an active and rapidly developing field. As the density and operating speed of CMOS VLSI chip increases, power dissipation becomes more significant ..."

Dual-Threshold Design of Sub-threshold Circuits
"... Abstract—Dual threshold voltage (Vth) design is a common method for reducing leakage power in above-threshold circuits. This research shows that it is also effective in reducing energy per cycle of sub-threshold circuits. We first study the single-Vth design theoretically and by simulations, and fin ..."

Low Power Synthesis of Dual Threshold Voltage CMOS VLSI Circuits
, 1999
"... The use of dual threshold voltages can significantly reduce the static power dissipated in CMOS VLSI circuits. With the supply voltage at 1V and threshold voltage as low as 0.2V the subthreshold leakage power of transistors starts dominating the dynamic power. Also, many times a large number of devi ..."

Abstract Screening VDSM Outliers using Nominal and Subthreshold Supply Voltage IDDQ
"... Very Deep Sub-Micron (VDSM) defects are resolved as Statistical Post-Processing ™ (SPP) outliers of a new IDDQ screen. The screen applies an IDDQ pattern once to the Device Under Test (DUT) and takes two quiescent current measurements. The quiescent current measurements are taken at nominal and at s ..."

Minimizing Energy of Integer Unit by Higher Voltage Flip-Flop: VDDmin-Aware Dual Supply Voltage Technique
"... Abstract — To achieve the most energy-efficient operation, this brief presents a circuit design technique for separating the power supply voltage (VDD) of flip-flops (FFs) from that of combinational circuits, called the higher voltage FF (HVFF). Although VDD scaling can reduce the energy, the minimu ..."
