The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a ...

Let me shatter your confidence in simplicity! You think that applying an op amp is as simple as using a non-inverting circuit: Let me shatter your confidence in simplicity! You think that applying an ...

Current-feedback (CFB) op amps have earned their reputation in many applications that need bandwidth, without compromising other noise and high-speed characteristics. They have served these needs ...

In Chapter 7 we studied some of the basic properties of operational amplifiers. There are an enormous number of ways that op amps can be applied to process analog signals. In this chapter we will ...

This book is designed for students who are taking their first course in analog electronics in either a two-year or four-year program. The prerequisites are a DC-AC course; a basic knowledge of algebra ...

This is the second part in our series explaining the nature, characteristics, benefits, and caveats of composite amplifiers. The four parts of the series include: Part One: When Cascaded Amplifiers ...

In our quest to describe the instrumentation amplifier, we began by exploring electromagnetic interference (EMI) and what to do about it. We then examined the basis of instrumentation amplifiers, ...
