Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Before discussing the various op-amp architectures, it is important to clarify what is meant by the term “precision” op amp. This term typically relates to the input offset voltage of the amplifier.

Operational amplifiers or op amps are becoming a crucial building block in high-accuracy and high-bandwidth sensor interfaces by providing precision signal conditioning without calibration, thus ...

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 ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
