Abstract: In this paper we present a simple ultra low-voltage and high speed D flip-flop. The delay of the static differential flip-flop presented is less than 12% compared to conventional differential CMOS flip-flops. The presented circuits have been simulated using Hspice and are valid for 90nm TSMC CMOS process. The proposed high-speed and ultra low-voltage flip-flop can be used for any digi...

This paper presents an analog VLSL circuit for implementation of Artificial Neural Networks (ANNs ).

In this paper we present a novel static differential ultra low-voltage (ULV) CMOS logic style for High-Speed applications . The proposed logic style is aimed for high speed serial adders in ultra low-voltage applications. The differential ultra low-voltage inverter presented have less than 10% of the delay than standard CMOS inverters for supply voltages less than 500mV . The simulated data pre...

Using microfabrication techniques, we extracted individual channels of 3-kelvin (3-K) phase superconductivity in Sr2RuO4-Ru eutectic systems and confirmed odd-parity superconductivity in the 3-K phase, similar to pure Sr2RuO4. Unusual hysteresis in the differential resistance-current and voltage-current characteristics observed below 2 K indicates the internal degrees of freedom of the supercon...

Spin-polarized transport through a single-level quantum dot interacting with a local phonon mode is studied in the frame of the nonequilibrium Green-function technique. It is shown that strong electron–phonon interaction gives rise to a significant current suppression, to additional resonance peaks in the differential conductance as well as to oscillations of the tunnel magnetoresistance. Also,...

The empirical differential equation that describes the kinetics of monazomycin-induced voltage-dependent conductance is derived using a standard chemical kinetic formulation and the assumption that monazomycin entry into and exit from the membrane is autocatalytic. The predicted form of gating currents is shown and numerical calculations for this process are made using a range of values for two...

This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

BACKGROUND AND OBJECTIVE Interaction of intravenous anaesthetic agents with voltage-dependent potassium channels significantly correlates with clinical concentrations. If potassium channels were to play an important part in anaesthesia, one might expect different effects at the molecular level of those anaesthetics that show different clinical effects. Our aim was to analyse the interaction of ...

This paper presents the design and preliminary results of a full differential sample-and-hold circuit based on the "flipped voltage follower" (FVF) cell. The heart of this circuit is a fully differential low-voltage OTA based on FVF technique. The use of the FVF reduces the supply power requirements in the OTA. To overcome input sampling switches limitation imposed by the low supply voltage we ...

Single sodium channel currents were analysed in cell attached patches from single ventricular cells of guinea pig hearts in the presence of a novel cardiotonic compound DPI 201-106. The mean single channel conductance of DPI-treated Na channels was not changed by DPI (20.8 +/- 4 pS, control, 3 patches; 21.3 +/- 1 pS with DPI, 5 mumol/1,3 patches). DPI voltage-dependently prolongs the cardiac so...
