BACKGROUND The SCN5A encoded sodium current (I(Na)) generates the action potential (AP) upstroke and is a major determinant of AP characteristics and AP propagation in cardiac myocytes. Unfortunately, in cardiac myocytes, investigation of kinetic properties of I(Na) with near-physiological ion concentrations and temperature is technically challenging due to the large amplitude and rapidly activ...

As the power consumption of modern highperformance microprocessors increases beyond 100W, power becomes an increasingly important design consideration. This paper presents a novel technique to simulate power supply voltage variation as a result of varying activity levels within the microprocessor when executing typical software. The voltage simulation capability may be added to existing microar...

New low-power Level Shifter (LS) circuit is designed by using sleep transistor with Multi Threshold CMOS (MTCMOS) technique for robust logic voltage shifting from sub-threshold to abovethreshold domain. MultiSupply Voltage Design (MSVD) technique is mainly used for energy and speed in modern system-on-chip. In MSVD, level shifters are required to allow different voltage supply to shift from the...

We successfully fabricated nanowire-based complementary metal-oxide semiconductor (NWCMOS) inverter devices by utilizing n- and p-type Si nanowire field-effect-transistors (NWFETs) via a low-temperature fabrication processing technique. We demonstrate that NWCMOS inverter devices can be operated at less than 1 V, a significantly lower voltage than that of typical thin-film based complementary m...

Consolidation of shunt capacitors plays an important role in radial distribution networks. Among many of their merits, line loss and total harmonic distortion (THD) reduction, voltage profile improvement and reactive power compensation can be the salient specifications of shunt capacitors. Studies show that non-optimal locations shunt capacitor units lead to increase loss, together with bad eff...

Nowadays, integration of new devices like Distributed Generation, small energy storage and smart meter, to distribution networks introduced new challenges that require more sophisticated control strategies. This paper proposes a new technique called Optimal Coordinated Voltage Control (OCVC) to solve a multi-objective optimization problem with the objective to minimize the voltage error at pilo...

A low-power technique for digital filtering referred to as adaptive error-cancellation (AEC) is presented in this paper. The AEC technique falls under the general class of algorithmic noise-tolerance (ANT) techniques proposed earlier for combating transient/soft errors. The proposed AEC technique exploits the correlation between the input and soft errors to estimate and cancel out the latter. I...

Out of the various existing ultrasonic power measurement techniques, the radiation force balance method using microbalance is most widely used in low power (below 1 W) regime. The major source of uncertainty associated with this technique is the error in ac voltage measurement applied to the transducer for the generation of ultrasonic waves. The sources that deteriorate the ac voltage measureme...
