Motivation & ObjectiveMotivation & 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.

PlanPlan

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 StatusProject 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...

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.
