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 ...

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 ...

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 ...

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 ...

Op-amp performance is disrupted by EMI in a variety of ways. Reducing EMI in amplifiers using filters. How to mitigate EMI in Class-D audio amps. In this article, electromagnetic interference (EMI) ...

Along with temperature extremes, electromagnetic interference (EMI) is a pervasive issue in automotive, industrial, and even medical environments as it can stimulate noise-induced errors, disrupt ...
