Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

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 ...

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 ...

Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...

AWR® has announced that Nuhertz Filter (a filter synthesis and analysis software from Nuhertz Technologies®) can be integrated with AWR's Microwave Office® high-frequency design suite. The company ...
