Op-amp circuits have a feedback loop, but sometimes it is advantageous to improve closed-loop performance by including another amplifier within the op amp's feedback ...

The operational amplifier (op amp) is the fundamental building block of all types of analog circuits. There are literally thousands of different ones available from dozens of vendors, ranging from ...

We have covered enough of the work of [Ken Shirriff] on these pages to know that when he publishes something, it will be a fascinating read and work of the highest quality. And so it is with his ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...

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 ...

What is driving the power vs. performance tradeoffs? How to improve the op-amp bandwidth-to-power ratio. How noise, distortion, and other factors impact the power/performance design decisions. The ...

The ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...

A fresh lineup of CMOS operational amplifiers targets accuracy, speed, and versatility across automotive, industrial, and ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

ROHM has introduced two new CMOS operational amplifier series, adding 17 devices to its portfolio in a move aimed at ...
