Study of subthreshold behavior of FinFet
The study of subthreshold behavior of Metal Oxide Semiconductor Field Effect Transistor (MOSFET) is critically important in the case of submicron devices for the successful design and implementation of digital circuits. Fin Field Effect Transistor (FinFET) is considered to be an alternate MOSFET …

Superlattice-source nanowire FET with steep Subthreshold characteristics
The non-scalable room temperature 60 mV/dec subthreshold swing of a conventional MOSFET is a fundamental limit to the continuation of transistor power scaling. In order to further reduce transistor power consumption and transistor footprint, new subthreshold transport mechanisms other than …

The Effect of Subthreshold Vibration on Lateral Reactive Balance
Previous research has indicated that subthreshold vibratory noise improves standing balance control in a diverse range of populations (i.e., young adults, older adults, and persons with diabetic neuropathy). However, there is limited literature examining whether these effects extend to reactive …

Subthreshold leakage control techniques for low power digital circuits
… trends in future technologies will cause subthreshold leakage currents to become an increasingly large component of total power dissipation. As a result, new techniques are needed in order to provide high performance and low power circuit operation. This dissertation develops new circuit …

Temperature robust programmable subthreshold circuits through a balanced force approach
The subthreshold region of operation has simple physics which allows for a balanced-force approach to behavioral modeling that has shown to be robust to temperature, and a model that encapsulates MOSFET behavior across all operational regions has been developed. The subthreshold region of operation …

Reducing Subthreshold Leakage Power Through Hybrid MOSFET-NEMS Power Gating
… and drain while in the off state, eliminating subthreshold leakage current. The NEMS switch is slower to operate and only has a finite number of switching before breaking. They should be switched with caution. Proposed in this thesis is a hybrid power gating model wherein a MOSFET is placed in …

Power Reduction of Digital Signal Processing Systems using Subthreshold Operation
… processing is to operate the circuit in the subthreshold region, where the supply voltage is lower than the threshold voltage of the transistors. Subthreshold operation greatly reduces the power and energy consumption, but also decreases the maximum operating frequency. Many digital signal …

A 0.45 V low power high PSRR subthreshold CMOS voltage reference
… low power requirement is to operate MOSFETs in subthreshold region. Most often, forward biased PN-junctions of BGRs are substituted with MOSFETs biased in the subthreshold region and achieves a supply voltage down to 0.6 V.\par This paper presents a sub-1V voltage reference circuit that has only …

Ultra Low Power SubThreshold Device Design Using New Ion Implantation Profile
… circuit operates at higher supply voltage. Subthreshold circuit operates at lower supply voltage and these kind of effects will not be a serious issue. Since subthreshold circuit will operate at much lower supply voltage then devices for subthreshold circuit does not require halo and …

“Evaluation and impact of subthreshold contrapolar symptoms during a Major Depressive Episode in unipolar and bipolar patients”
… depressive episode (MDE) experience co-occurring subthreshold hypomanic symptoms. Although these presentations - commonly referenced as “mixed depressive states”- have been described since the Classical Age, an operational definition of mixed depression was not included in the official psychiatric …
