Timed Shannon circuits have been proposed as a synthesis approach for a low power optimization technique at the logic level since overall circuit switching probabilities may be reduced. An improvement in the application of this principle for multi-output circuits is presented. Techniques that trade area for power reduction and a method for minimizing the overall circuit switching probability ar...

A macro-model is a simplified model that emulates functional characteristics of a device or circuit, and widely used in system-level simulation. In this paper, macro-model based SPICE simulation of DC/DC switching regulators is presented. Macro-models of a power switch and Pulse Width Modulation (PWM) control circuit are described. Two simulation examples are given to demonstrate the capability...

This paper describes a secondary side resonant converter with particular suitability to step up and high power applications. A description of the basic circuit is followed by a detailed description and some important developments building upon the basic circuit, including inversion and bi-directional configurations. Efficiency is very good (≈94%) as a result of the zero voltage switching and ze...

The article tackles the problem of quality of service assurance in photonic networks. The idea of multi-service photonic network model with the coexistence of optical circuit and packet switching mechanisms and cell communication is used as a basis for service differentiation in the optical domain. Cell loss ratio as a key performance indicator determines the required optical switching mechanis...

According to the soft-switching pulsed SAW (Submerged arc weld) weld power supply based on the double closed-loop constant current control mode, a small signal mathematic model of main circuit of soft-switching SAW inverter was established by applying the method of three-terminal switching device modeling method, and the mathematic model of double closed-loop phase-shift control system circuit ...
