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 ...

Wideband filters with bandwidths in excess of an octave can be created by cascading a high-pass filter and a low-pass filter. In this design idea, nine-pole high-pass and low-pass filters have been ...

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 ...

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 ...

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, ...
