Well-defined experimental and simulating single peak to valley current density ratio (PVCDR) resonant tunneling electronic circuit (RTEC) element is proposed in this research. The variation of passive element value in RTEC structure is explored using simulation method, which obtains the optimum PVCDR values about 66. The simulating peak current density (PCD) value is such high as 38 mA. Even th...

A novel resonator using a composite right/left-handed (CRLH) transmission line (TL) is presented and its extraordinary resonant characteristics with an infinite-wavelength wave are discussed. The resonance corresponds to the zeroth-order on the analogy of the conventional mode numbering. The zeroth-order resonant characteristics and loss mechanism are fully described by the circuit theory and i...

Most power converters and equipments are developed to have power factor correction technology to improve their performance. A soft-switching two-switch resonant ACDC converter with hi...

The Synchrotron Radiation Source (SRS) at Daresbury Laboratory has a 600MeV Booster, fed by an energy storage power supply configuration (White Circuit). The design consists of two power supplies : an AC source to supply the losses to the parallel resonant circuits and a DC supply to fully bias the AC sinewave. In a recent modernisation of the control electronics, different methods of achieving...

This paper proposes a high efficiency DC-DC flyback converter with a resonant full-bridge inverter to use in PV systems. The flyback converter is composed of a resonant active-clamp circuit that limits the voltage stress and provides zero voltage switching (ZVS) turn-on and turn-off of the power switches. Therefore, the switching losses of the high frequency primary switches are negligible. A r...

Physically intuitive coupled-mode and equivalent electrical-circuit theories are described for synthesis of nanophotonic resonator/interferometer circuits, including a new phase law for general 4-ports. Synthesis of self-adaptive (highly-nonlinear) optomechanical systems based on light forces is introduced. ©2008 Optical Society of America OCIS codes: (230.5750) Resonators; (120.2440) Filters; ...

We propose and demonstrate both a binary and ternary adder circuit based on a resonant tunneling diode (RTD) and a bipolar transistor. The basic switching cell consists of an RTD in series with the base of a bipolar transistor. The RTD is used to set a threshold voltage for the switching of the transistor.

1. Introduction Resonators are the basic building blocks of rf filters and oscillators. Like any other circuit component, a resonator must be experimentally tested to determine its properties. The three fundamental characteristics of an rf resonator that have to be determined by measurement are: (1) resonant frequency, (2) coupling coefficient, and (3) unloaded Q factor.

Renewable energy generation systems, based on photovoltaic sources, currently represent the most suitable solution, for low power levels, to reduce the energy consumption produced by oil and gas. Moreover, they are becoming more and more attractive as the price per watt of the photovoltaic modules is decreasing. However, the conversion efficiency of commercial photovoltaic modules is still rath...

A flash analog-to-digital converter, consisting of resonant-tunneling ternary quantizers and ternary-to-binary encoder circuits, is proposed. SPICE simulation exhibits a possible 10-GHz operation with reduced device counts and power dissipation, which are due to its compact circuit configuration.
