Two new low-power, and high-performance 1bit Full Adder cells are proposed in this paper. These cells are based on low-power XOR/XNOR circuit and Majority-not gate. Majority-not gate, which produces Cout (Output Carry), is implemented with an efficient method, using input capacitors and a static CMOS inverter. This kind of implementation benefits from low power consumption, a high degree of reg...

In this paper, we present a novel compact rf or ac power generator that uses a resonant driving scheme without the necessity for any matching device. The developed unit also doesn't need any expensive high voltage power supply for generating output voltages in the range of some hundred volts typically required for the function of trapping devices. The high efficiency of the generator allows ope...

Sn and Se doped InAs nanowires are characterized using a capacitance-voltage technique where the threshold voltages of nanowire capacitors with different diameter are determined and analyzed using an improved radial metal-insulator-semiconductor field-effect transistor model. This allows for a separation of doping in the core of the nanowire from the surface charge at the side facets of the nan...

This paper presents the design and simulation of a Full Bridge Soft Switched DC-DC Converter, working with an internal frequency of 20khz with an output power of 5kw. Since the ZVS range is independent of the switch capacitance, IGBT’S are used by adding the external capacitors to the switches without increasing the switching losses. However, it is not easy to design a hard-switched converter s...

This paper presents an electronically tunable current/voltage mode universal biquad filter using current controlled current conveyor transconductance amplifiers (CCCCTAs). The proposed filter employs only two CCCCTAs and two grounded capacitors. The proposed filter can simultaneously realize low pass (LP), band pass (BP) and high pass (HP) responses. Realization of band reject (BR) and all pass...

Optimal power flow is an optimizing tool for operation and planning of modern power systems. This paper presents the solution of the optimal power flow (OPF) using particle swarm optimization (PSO). The main goal of this paper is to verify the viability of using PSO problem composed by different objective functions. This OPF problem involves the optimization of various types of objective functi...

A physics based compact model describing the fatigue behavior of ferroelectric capacitors has been developed. Fatigue is a gradual decrease of detectable polarization with increasing number of polarization cycles. This can be caused by trapped charges which pin dipoles near the interface to the electrode. In order to polarize those pinned dipoles they have to be separated from the trapped charg...

Load currents through the power and distribution transformer and line impedances cause voltage drops, which reduce voltage magnitude at the loads. Voltage magnitudes at service locations must be maintained within specified ranges. This is accomplished in both fixed designs of the system (e.g., conductor selection, substation and distribution transformer tap settings, fixed capacitor banks) and ...

Introduction Tight dynamic tolerances for supply voltages of next-generation microprocessors and DSPs at high slew-rate transitions from sleep mode to full-power operation and backwards require fast-transient-response power supplies along with a special decoupling technique. The analysis and optimization of synchronousbuck converters with hysteretic controllers at load-current transients has be...
