Threshold Voltage Control Schemes in Finfets [PDF]
International Journal of VLSI Design & Communication Systems, 2012 Conventionally polysilicon is used in MOSFETs for gate material. Doping of polysilicon and thus changing the workfunction is carried out to change the threshold voltage. Additionally polysilicon is not favourable as gate material for smaller dimensional devices because of its high thermal budget process and degradation due to the depletion of the doped

Voltage controlled memristor threshold logic gates [PDF]
2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016 In this paper, we present a resistive switching memristor cell for implementing universal logic gates. The cell has a weighted control input whose resistance is set based on a control signal that generalizes the operational regime from NAND to NOR functionality. We further show how threshold logic in the voltage-controlled resistive cell can be used to

Effect of oxide interface roughness on the threshold voltage fluctuations in decanano MOSFETs with ultrathin gate oxides [PDF]
, 2000 In this paper we use the density gradient (DG) simulation approach to study, in 3D, the effect of local oxide thickness fluctuations on the threshold voltage of decanano MOSFETs on a statistical scale.

A Voltage Multiplier With Adaptive Threshold Voltage Compensation
IEEE Journal of Solid-State Circuits, 2017 A voltage multiplier (VM) with adaptive threshold voltage compensation is presented to enhance the power conversion efficiency (PCE). It is fabricated in a 0.18- $\mu \text{m}$ CMOS process. With the input frequency of 402 MHz and a load resistor of 30 $\text{k}\Omega $ , this VM achieves the PCE of 31.9% with the input power of −1 dBm, and ...

Fabrication of low threshold voltage microlasers
Electronics Letters, 1992 Summary form only given. The voltage required for threshold in vertical cavity surface emitting lasers (VCSELs) has been reduced to 1.7 V. Molecular beam epitaxy (MBE) was used to grow 30 pairs of n-doped AlGaAs/AlAs bottom mirrors and the active p-n junction with a 1- mu m p-doped top contact.
