In this paper simple current-mode single-input and dual-input integrator/differentiator structures using differential voltage current conveyors (DVCC) are proposed. They are composed of one DVCC and two or three passive components in single-input or dual-input realizations, respectively. The effects of the terminal tracking errors in a non-ideal DVCC are analyzed, which shows that the time constants (tau) are practically active-insensitive. Compensation design equations are derived for correcting the value of tau that was altered due to the terminal tracking errors of the DVCC. The performances of the circuits are demonstrated on SPICE platform.
