GROUNDED CAPACITOR FIRST-ORDER FILTERS INCLUDING CANONICAL FORMS

Abstract

Six novel first-order filters with voltage input, voltage and current outputs employing a single fully differential current conveyor are proposed, three of which are canonical. All the circuits employ a grounded capacitor; and realize all-pass, low-pass and/or high-pass functions. Some circuits provide five distinct first-order functions or six functions with additional output stages. The proposed circuits are verified through computer simulation results.
