Experimental tests are carried out under several working conditions in order to understand the main advantages and drawbacks of the switch. Finally, actual ZV applications, such as a step-down ZV quasi-resonant converter (QRC) and a TV deflection circuit, are presented and discussed.","PeriodicalId":301003,"journal":{"name":"Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

In principle, vertical MOSFETs with different layer designs show a similar DC behaviour to conventional lateral devices. The vertical planar doped barrier MOSFET (PDBFET) exhibits the highest transconductance already for longer channel length. On the other hand, caused by the large gate contact overlap to source/drain layers, the different vertical transistor versions show only low values of the cutoff frequency compared to lateral devices. The reduction of this overlap and an increase of the oxide thickness between the gate contact and the substrate material can considerably improve the small signal behaviour of vertical MOS transistors. For example, for optimized vertical homogeneously doped transistors with 130 nm channel length cut off frequencies of over 65 GHz have been predicted at V/sub ds/=2.0 V.","PeriodicalId":301003,"journal":{"name":"Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

The two application types have distinct requirements in terms of delay to support interactive services, particularly under shared virtual environment. Conversational interactive type application continuous media is mainly focused, a limited delay is required for achieving real-time service guarantees and for maintaining temporal relationship, or synchronization. In this paper, we apply the internet delay model to the conversational type application for distributed multimedia data under shared virtual environment on the internet to analyze the performance of the bounded delay value. The simulation results show the delay variation of continuous multimedia data apparently at the clients and a server under dynamic case consideration which represents the delay characteristic of the application on the internet.","PeriodicalId":301003,"journal":{"name":"Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

The first one is a high-voltage solar cell with only vertical p-n junctions. Therefore, the photocurrent value of this structure and-consequently-the efficiency are low because of the small active p-n junction area. In order to improve the main parameters of this structure-particularly the photocurrent and the efficiency-a new structure of high-voltage solar cells, combining both horizontal and vertical p-n junctions is suggested. This structure has been elaborated by combining liquid phase epitaxy with gas-phase zinc diffusion technologies, and was grown on semi-insulating GaAs substrates with /spl rho/=10/sup 12/ /spl Omega//spl middot/cm. This new structure has shown better parameters than the parameters of the high-voltage solar cell with only vertical p-n junctions. It exhibits appreciable values of photocurrent and output voltage. Furthermore, this structure provides both high short wavelength sensitivity, and independent efficiencies of spectral composition of solar radiation. Therefore, it can be successfully utilized in many aspects of modern science and technology, particularly as power supplies in high-located areas, and as photoacceptors for ultraviolet radiation.","PeriodicalId":301003,"journal":{"name":"Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.

Improvements ranging from 20 to 30 times in HC lifetime were achieved by the introduction of sufficiently high N/sub 2/ (I/I) doses. It was found that for NMOSFET's the HC degradation correlates inversely to the initial interface state density introduced by the N/sub 2/ I/I process. We believe that the increased initial interface state density and the reduced hot carrier degradation both stem from the reduced hydrogen concentration at the Si-SiO/sub 2/ interface with increasing N/sub 2/ dose.","PeriodicalId":301003,"journal":{"name":"Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat.
