Jarvis Communication Corporation Background Jarvis Communication is a start-up firm that develops‚ manufactures‚ and markets a miniature telephone. Last year’s sales revenue was $6.5 million‚ resulting in its first profitable year in its first three years of business. The phone is unique because it is only two inches long‚ weighs two ounces‚ and a miniature receiver is worn in the ear. The phone speaker and microphone carry out all the normal functions of a phone (except dialing) without the use

of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are packaged individually‚ but many more are found embedded in integrated circuits. The transistor is the fundamental building block of modern electronic
