Abstract

A novel current-mode second-order notch filter configuration is proposed. The presented circuit uses single current differencing buffered amplifier (CDBA) and minimum passive components. High output impedance of the proposed filter enables the circuit to be cascaded without requiring any impedance matching device. It has also low passive sensitivities. The theoretical results are verified with PSPICE simulations. (C) 2003 Elsevier Ltd. All rights reserved.
