In recent years, nonlinear circuit analysis techniques have been extensively investigated. One of the most important reasons is the application development of solid-state devices at microwave frequencies. Different methods have been used to analysis large signal behavior of these devices. In this paper load-pull curves (one of design requirement) are obtained using Volterra series. The main adv...

The advantages of fully-depleted (FD) SOI CMOS technology in comparison to bulk Si regarding analogue circuit design have been reported in [1]. Most of them relate to the combination of the reduced capacitance of SOI technology with the better transconductance (gm) over drain current (IDS) ratio due to the reduced FD body factor, which provides enhanced bandwidth and gain, resulting in very sig...

In this paper a novel multilevel current source inverter structure is proposed. This inverter is likely to be used in low/medium power applications. The proposed topology is analyzed and then compared with conventional inverters in order to validate the superiority of the proposed inverter. In this topology, all the desired current levels can be obtained using lower number of circuit devices. T...

The scale-down of CMOS technology has been the driving force for the realization of high-performance very-large scale integration (VLSI) systems [1]. As the MOSFET channel length is reduced to 50nm and below, the suppression of the off-state leakage becomes an increasingly difficult technological challenge. However, the off-state leakage can be utilized as the operating current to achieve ultra...

Turn-on efficiency is the main concern for silicon-controlled rectifier (SCR) devices used as on-chip electrostatic discharge (ESD) protection circuit, especially in deep sub-quarter-micron CMOS processes with much thinner gate oxide. A novel double-triggered technique is proposed to speed up the turn-on speed of SCR devices for using in on-chip ESD protection circuit to effectively protect the...

in this research, active capacitance circuit and the feature of negative resistance are analysed in details. also, a new active filter is presented based on active capacitance circuit. for simulations, we used matlab and advanced design system(ads). proposed active filter (rf) is a narrow band filter. the results of simulation shows some aspects of sustainability and low noise feature. the circ...

the well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. a new model that was previously proposed by the authors that combines a mass with a pulley (mp) is shown to simulat...
