The following is Part 1 of a four-part series. The basic one-op-amp differential amplifier consists of one op-amp and four resistors. Yet few have contemplated the depth of its complexity. It is ...

What is hard about analyzing feedback circuits is the extraction from the circuit diagram of the simple block diagram found in active circuits and control textbooks. To start with a relatively easy ...

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 ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
