The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...

In feedback systems loop gain, open loop gain, and closed loop gain are all concepts that are important to understand. The transfer function for closed loop gain is: The quantity A is known as the ...

This time I’ve opened up the way-back machine and unearthed a piece I first published nearly 20 years ago, when I was at the Burr-Brown Corporation. Op-amp compensation is still a topic that surfaces ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
