Project Presentation Power optimization of an IR remote control Presented by Hazem Awad

Motivation & Objective Current Remote control devices operate on 2 or 4 AA batteries. Hence these devices consume a lot of energy. Goal is to reduce the number of batteries used and/or reduce power dissipation. Concern is with power reduction and not speed.

Plan Optimization will be done at the transistor level. This requires use of principles learned in this course. Using existing designs, I will attempt to re- size the transistors available in order to reduce power dissipation and/or power requirements If needed, I will attempt to redesign the device using one of the low-power logic families such as LVDCSL.

Project Status Found the device schematics on the web. Started preliminary analysis of design. In the process of deciding if there is a need to use another logic family or simply use transistor sizing techniques.

Time Permitting... Time permitting, I will try to optimize devices using 2 AA batteries. Currently, I am concentrating of devices that use 4 AA batteries. Time permitting, I will attempt to retain the speed performance of the device as well as reducing its power consumption.
