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 ...

EMC engineers are often called on to design low-pass filters for client projects, which is usually required to meet radiated susceptibility tests. While the most common radiated-immunity standard (IEC ...

When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...

As operating speeds increase, the effect of the internal impedance at the input nodes become more critical to achieving the desired frequency response. The most common issues revolve around the common ...
