Bipolar Junction Transistors Flashcard

Front

What are the two types of bipolar junction transistors (BJT)?

Back

NPN and PNP

Front

What is the function of the emitter in a BJT?

Back

To supply majority charge carriers

Front

In a common emitter configuration, what is the input signal applied between?

Back

Base and emitter

Front

What happens when the transistor is in cutoff condition?

Back

It acts like an open switch.

Front

What is the primary purpose of biasing in a BJT?

Back

To establish a fixed level of current and voltage

Front

What is the relationship between collector current (IC), base current (IB), and emitter current (IE)?

Back

IE = IC + IB

Front

What is the active region of a BJT used for?

Back

Amplification

Front

What does the term 'beta' (β) refer to in a BJT?

Back

Current gain

Front

Which configuration has the highest input resistance? Options: Common base, Common emitter, Common ground, Common collector

Back

Common collector

Front

What is the effect of negative feedback in amplifiers?

Back

Improves stability
