On Advanced Current Conveyor Applications Having Capacitor Connected to Current Input Terminal

Paper in proceedings (conference paper)

This paper discusses novel solutions of active building blocks (voltage-mode differentiator, all-pass filter) operating with current conveyors with grounded capacitor having intentionally connected to the current input terminal X. Because of real non-zero resistance of this current input terminal, the features of application are usually problematic. Proposed solutions bring elimination of these disadvantageous effects. Therefore, this work extends the exploitation of current conveyor-based building blocks and their applications. The current-controlled differential difference current conveyor was used in our designs and application of inverse inverting band-pass filter prepared for verification and implementation of presented differentiator. All theoretical evaluations are supported by PSpice analysis with CMOS models and macromodels representing used concepts and approaches.
