Low Passive Component-Count Current Follower-Based Current-Mode Second-Order Notch Filter

A realization of a current-mode second-order notch filter using current followers (CF s ) and a minimum number of passive elements is proposed. The proposed filter has a high output impedance, consequently it can be cascaded without using additional buffers. The filter displays low incremental passi...

Zusammenfassung:A realization of a current-mode second-order notch filter using current followers (CF s ) and a minimum number of passive elements is proposed. The proposed filter has a high output impedance, consequently it can be cascaded without using additional buffers. The filter displays low incremental passive sensitivities. Moreover, if the passive element values are properly chosen, the circuit permits also the realization of allpass response. The SPICE simulation results are given to verify the theoretical predicted behaviors.
