Reducing power in using different technologies using FSM architecture

As in today’s date fuel consumption is important in everything from scooters to oil tankers, powerconsumption is a key parameter in most electronics applications. The most obvious applications for whichpower consumption is critical are battery-powered applications, such as home thermostats and securitysystems, in which the battery must last for years. Low power also leads to smaller power supplies, lessexpensive batteries, and enables products to be powered by signal lines (such as fire alarm wires) loweringthe cost of the end-product. As a result, low power consumption has become a key parameter ofmicrocontroller designs . The purpose of this paper is to summarize, mainly by way of examples,what inour experience are the most trustful approaches to lowpower design. In other words, our contributionshould not be intended as an exhaustive survey of the existing literature on low-power esign; rather, wewould like to provide insights a designer can rely upon when power consumption is a critical constraint.Wewill focus on the reduction of power consumption on different technologies for different values ofoicapacitance and also compare power saving in technologies.
