Amplifiers
2.1 AMPLIFIER FUNDAMENTALS
2.1.1 Gain
This chapter focuses on the analysis and design of several basic amplifier circuits. Not only is the amplifier circuit a fundamental building block in linear circuits, but the analytical techniques introduced in this chapter will greatly enhance your ability to analyze the circuits presented in subsequent chapters. Regardless of the specific circuit application (e.g., summing circuit, active filter, voltage regulator, and so forth), the op amp itself is simply an amplifier. Therefore, a thorough understanding of op amp behavior in circuits designed specifically as amplifiers will provide us analytical insight that is applicable to nearly all op amp circuits.
An amplifier generally ...
