You can use three discrete transistors to build an operational amplifier with an open-loop gain greater than 1 million (Figure 1). You bias the output at approximately one-half the supply voltage ...

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

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Component distributor Richardson RFPD has prepared a couple of documents on the options available for designers of RF amplifiers. Rather than in-depth, they are a useful introduction to the different ...

Members can download the PDF ebook. One day, back about 1966, I was going up the elevator at 285 Columbus Avenue in Boston to look at some production problems on Philbrick’s fifth floor. And who was ...

Why discretes tend to win out over ICs when it comes to designing ‘folded cascode’ charge amplifiers. By Tolga Aydemir Integrated circuits (ICs) are vital in helping to reduce the cost, size and ...
