Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two f… ...

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.

1. The traditional inverting op-amp summer configuration exploits the low-impedance node (virtual ground) at the inverting input. The circuit is easy and straightforward to analyze and design with ...

The op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.

What is circuit grounding? Engineers use the word “ground” in every electronic circuit to denote some part of a system or structure that is “ neutral,” or zero potential. Unfortunately, we often think ...
