Dual-input current-mode integrator and differentiator using single DVCC and grounded passive elements

Abstract

In this paper new simple dual-input current-mode integrator/differentiator structures using differential voltage current conveyor (DVCC) are presented. The proposed circuits are composed of one DVCC and three passive components. The effects of the DVCC terminal tracking error are analyzed, which shows that the time constants (/spl tau/) are practically active-insensitive. Compensation design equations are derived for correcting the values of /spl tau/ that was altered due to the terminal tracking errors of the DVCC. The performance of the circuits are demonstrated on SPICE platform.
