In conversation, speakers become more like each other in various dimensions. This phenomenon, commonly called entrainment, coordination, or alignment, is widely believed to be crucial to the success and naturalness of human interactions. We investigate entrainment in four acoustic and prosodic dimensions. We explore whether speakers coordinate with each other in these dimensions over the conver...

This paper aims at to develop floating gate MOSFET (FGMOS) based low voltage, voltage-mode and current-mode circuits operating at ± 0.75 V supply voltages. The utility of FGMOS for low voltage applications lies in its threshold voltage tunability. FGMOS based low voltage current mirror and its subsequent use in the development of second-generation current conveyor is presented which in turn has...

in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...

In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...

InGaP/InGaAs doped-channel direct-coupled field-effect transistor logic (DCFL) with relatively low supple voltage is demonstrated by two-dimensional analysis. In the integrated enhancement/depletion-mode transistors, subband and two-dimensional electron gas (2DEG) are formed in the InGaAs strain channels, which substantially increase the channel concentration and decrease the drain-to-source sa...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...
