Current Mode Biquad Filters Using CFOAs: Additional New Realizations
Dinesh Prasad, D.R. Bhaskar and A.K. Singh

The authors propose three new current-mode biquad filters using two CFOAs, two grounded capacitors and two to four resistors. The active and passive sensitivities of the proposed configurations are low. The validity of the proposed new bi-quad filters is established by SPICE simulations.

Keywords: Current feedback operational amplifiers, current mode signal processing, current-mode filters.
