Abstract
An active RC voltage-mode circuit that mimics the behavior at low frequency of a bandwidth-tunable bandpass filter as realized by a double-tuned circuit is converted to a current-mode circuit using commercially available current-feedback op amps. Analyses and simulations show that the new current-mode circuit can operate relatively accurately in the neighborhood of 300 kHz using passive elements determined by ideal analysis
