Ease of Use:

Overview:: One of a set of presentations describing the behavior of semiconductor devices.
This applet shows how the base of a BJT behaves under a variable set of
conditions. It provides EE students with the ability to interact with a working
model of the BJT base behavior.
Type of Material:: Tutorial with simulation, visulaization, problem solving and review test.
Recommended Uses:: Supplement class lectures and text
Technical Requirements:: Java enabled browser
Identify Major Learning Goals:: Understanding one aspect of basic BJT behavior. The student should be able to
describe the effect variations in the base electrical and semiconductor
parameters.
Target Student Population:: 2nd & 3rd year EE & ECE students
Prerequisite Knowledge or Skills:: Understanding of basic microelectronics behavior. Some circuit analysis.

Rating:
Strengths:: Provides visualization, simulation, exercises, etc. The material is generally
part of the core curriculum in Electrical/Computer Engineering. The graphics are
attractive and get the user's attention.
Concerns:: Some portions of the presentaion are incomplete, but the presentation is still
very usable.

Rating:
Strengths:: Good supplement to text & lecture; provides opportunities for students to
explore. The material can be easily incorporated into homework assignments,
group assignments, and in a tuterial fashion.
Concerns:: Students must review written material before they simply start clicking on
applet. Initial guidance must be provided by an instructor.

Rating:
Strengths:: Software is robust and easy to use.
Concerns:: A teacher's manual could assist instructors in choosing how to use the material
effectively.

Other Issues and Comments:: This applet should help students better understand the topic. It offers
opportunities for visual learners, drill and practice, explorations, and skill
testing
