There are a lot of ways to achieve large current pulse power supply, and the more common way is to adopt the inverter switching circuit to achieve pulse power supply. The core of the NC power supply design of large current and wide frequency pulse in SEAM is using two-stage modulation. Combined with inverter technology, DC chopper technology and NC technology, it not only can achieve the adjust...

Transmission Line Pulse is a short pulse (25ns to 150ns) measurement of the current-voltage (I/V) characteristics of the ESD protection built into an integrated circuit. The short TLP pulses are used to simulate the short ESD pulse threats and integrated circuit must tolerate without being damaged. In this work the fundamental principles of how the TLP pulse is generated and used to create I-V ...

We present a silicon model of an axon which shows promise as a building block for pulse-based neural computations involving correlations of pulses across both space and time. The circuit shares a number of features with its biological counterpart including an excitation threshold, a brief refractory period after pulse completion, pulse amplitude restoration, and pulse width restoration. We prov...

In this paper, a novel pulse tripling circuit (PTC) is suggested, to upgrade polygon autotransformer 12-pulse rectifier (12-PR) 36-pulse (36-PR) with low power rating. The kVA rating of the proposed PTC lower compared conventional one (about 1.57% load power). Simulation and experimental test results show that total harmonic distortion (THD) input current suggested 36-PR less than 3%, which mee...

'HE authors of the present paper have recently described a method for the experimental determination of the disintegration curve of Tnesotrons and have given a preliminary account of the results obtained. ' The method has been since improved and a new and more extensive set of data has been taken. A summary of the riew results is presented here. The experimental arrangement, which is similar in...

A new type of compact chirped-pulse-amplification circuit for high-power amplification of femtosecond pulses in an optical fiber is demonstrated. This circuit is based on a novel pulse compressor, chirped-period quasi-phase-matching gratings in electric-field-poled lithium niobate. The main advantages of this circuit are simplicity, the small number of components, compactness, and wavelength co...

iran is a rather wide country, and, as a rule, the chrage per one call in s. t .d . (subscriber trunk dialing ) is required more compared with a local call , so, just after the opening of the std service widely in national telephone network, unconcerned use of the s. t. d. service has been caused on an incon- ceivable increase in telephone charge of th subscriber. this is a common problem for a...

In an x-ray preionised XeF(B~X) dischargeexcited laser driven by a magnetic-spiker sustainer circuit with a magnetic pulse compressor the influence of the various parameters on the optical pulse duration was experimentally investigated. Laser pulses at 2= 351 nm with a duration of 212 ns (FWHM) have been achieved in a NF3/Xe/Ne mixture by using very low (0.25 mbar) NF3 partial pressures in a to...

ABSTRACT Recent applications of pulse-coupled neural networks have demonstrated the need for a simple pulse-coupled neuron circuit which can easily be implemented in CMOS technology. The proposed cell uses a positive feedback circuit with two capacitors. One capacitor corresponds to the external sodium ion potential, and the other to the internal potassium ion potentid. This cell body circuit i...
