The low-frequency LC performance of a high-pass filter is strongly affected by the quality of the filter components. Typically, the inductor is the component that deviates most significantly from the ...
Setting out to design a higher order, high pass filter using the Sallen-Key single op amp topology will immediately run into a question of required amplifier bandwidth. This is most often set by the ...
Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...
