With the introduction of commercially available amplifiers using the current feedback topology by Comlinear Corporation in the early 1980’s, previously unattainable gain and bandwidths in a DC coupled ...

A power supply that I was examining used an opto-coupler in its feedback path for control of its output voltage. This is a commonplace and well established design approach, but the feedback loop’s ...

For the PDF version of this article, click here. Switching power supplies rely on feedback control loops to ensure the supply maintains the required voltage and current with varying load conditions.

FPGAs provide increased precision and performance to mitigate disturbances found in typical laser test beds. Taking high-precision measurements, such as those for molecular and atomic applications, ...
