Chopper amplifiers are generally considered as a perfect choice in applications where DC precision is mandatory. This kind of amplifier uses a continuous time modulation technique to exhibit extremely ...

Input bias current is a usually overlooked amplifier parameter that can have a significant effect on an amplifier circuit’s output accuracy. Sometimes the effect is small enough to be ignored, but ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

To ensure the stability of dc-dc converters, most power-system designers adhere to the common rule that input source impedance should be small compared to the converter's input impedance. Not all ...
