  • The need for operating circuits at increasingly higher speeds has always challenged designers. From radar and television systems in the 1940s to gigahertz microprocessors today, the demand for pushing circuits to higher frequencies has required a solid understanding of their speed limitations. In this chapter, we study the effects that limit the speed of transistors and circuits, identifying topologies that better lend themselves to high-frequency operation.

  • Power flow solutions are needed in both for planning and operation studies. Power flow studies for three phases balanced power system can be carried out using very efficient methods. Power flow analysis for certain type of power system network can be carried on by using several software that already been develop without manual calculation on this time. One of the software is MATLAB with its toolbox: Power System Analysis Toolbox. This software also uses numerical methods to do power flow analysis like Newton-Raphson and its modified form, Fast Decoupled Method.

  • This paper analyzes the role of the financial system for economic growth and stability, and addresses a number of core policy issues for financial sector reforms in emerging economies. The role of finance is studied in the context of a circuit model with interacting rational, forward- looking, and heterogeneous agents. Finance is shown to essentially complement the price system in coordinating decentralized intertemporal resource allocation choices from agents operating under limited information and incomplete trust.
