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 ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...
