Vertically stacked two-dimensional (2D) van der Waals (vdW) heterostructures based on graphene electrodes represent a promising architecture for next-generation electronic devices. However, their first-principles characterizations have been so far mostly limited to the equilibrium state due limitation of standard non-equilibrium Green's function approach. To overcome these challenges, we introd...

The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

This article discusses the very crucial subject of RFID TAGʹs stability. RFID equivalent circuits of a label can be represented as Parallel circuits of Capacitance (Cpl), Resistance (Rpl), and Inductance (Lpc). We define V(t) as the voltage that develops on the RFID label therefore making dV(t)/dt the voltage‐time derivative. Due to electromagnetic interference,...

In this paper a novel common mode separation technique for implementing fully differential current buffers is introduced.  Using the proposed method two high CMRR (Common Mode Rejection Ratio) and high PSRR (Power Supply Rejection Ratio) fully differential current buffers in BIPOLAR and CMOS technologies are implemented.   Simulation results by HSPICE using 0.18μm TSMC process for CMOS based st...

We report magnetotransport measurements in the NbN-magnetic topological insulator ${\mathrm{MnBi}}_{2}{\mathrm{Te}}_{4}$ (MBT)-NbN junction at low temperature. At 10 mK, nonlinear current-voltage characteristic of shows a tunneling behavior, indicating existence interfacial potential barriers within heterostructure. Under an out-of-plane perpendicular magnetic field, transition from negative to...

This paper presents a novel CMOS differential voltage current conveyor based on a wide linear range transconductor with common mode detection. The differential voltage current conveyor exhibits a wide dynamic input range of ±0.9V. It is used to realize an instrumentation amplifier, a multiple input single output filter, and a single input multiple output universal filter. PSPICE simulations of ...

A model on alpha-power law MOSFETs based source-coupled differential pair (SCDP) is discussed and a simple design procedure for realizing a linear CMOS SCDP transconductance element is proposed. The proposed or modified SCDP circuit using this procedure is an alternative to that of conventional SCDP and the circuit discussed has superior linearity for a wide range ±(0-300mv) of input differenti...

A thermo-morphic transition of a silicon nanowire (Si-NW) is investigated in vacuum and air ambients, and notable differences are found under each ambient. In the vacuum ambient, permanent electrical breakdown occurs as a result of the Joule self-heating arising from the applied voltage across both ends of the Si-NW. The resulting current abruptly declines from a maximum value at the breakdown ...
