Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...

Who is involved with simulating op-amp design and developing their datasheets? Clarifications on sometimes obtuse amplifier specifications. Pitfalls to avoid when interpreting ac specs. What to watch ...

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 ...

Abstract: A study is made of the integrated circuit operational amplifier (IC op amp) to explain details of its behavior in a simplified and understandable manner. Included are analyses of thermal ...

Abstract: Frequency compensation of two-stage integrated-circuit operational amplifiers is normally accomplished with a capacitor around the second stage. This compensation capacitance creates the ...

Achieving an optimal balance between high performance and power consumption in mobile-device designs is a tricky task, especially when it comes to operational amplifiers. What is driving the power vs.

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer, you ...

This week we are entering the wild world of Teenage Engineering’s OP-Z. The tiny little portable gadget is essentially its own music making platform with built-in instruments. However, it is also ...

Today’s circuit designers usually will need to design with analog circuitry on their boards, even if the core circuitry is Processor-based or a power supply design, MEMS/sensor or such. The problem is ...

Although I used op amps in many feedback loops over the years, the subject of transconductance op amps versus voltage feedback op amps has always intrigued me. Therefore, I thought it would be a good ...
