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 ...

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 ...

Two very desirable features for a precision measurement system based on an analog-to-digital converter (ADC) are high input impedance and a wide input range, ideally including or extending slightly ...
