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, ...
Ceramic resonators and filters occupy a practical middle ground in frequency control and signal conditioning, offering designers cost-effective alternatives to quartz crystals and LC networks. Built ...
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 ...
