Bandpass filters are indispensable in modern communication, radar, and imaging systems, serving to isolate desired frequency ranges while attenuating unwanted spectral components. Contemporary ...

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, ...

Switched-capacitor filters that are preset for a given bandwidth sometimes do not deliver the bandwidth or Q an application requires. By inverting the clock between two switched-capacitor bandpass ...

The Fraunhofer Institute for Integrated Circuits IIS has developed digitally tunable and reconfigurable RF filters. In a congested spectrum “devices that send and receive data must function reliably”, ...

Applications such as audio equalizers require bandpass filters with a constant maximum gain that's independent of the filter's quality factor, Q. However, all of the well-known filter ...
