INSENSITIVE VOLTAGE-MODE AND CURRENT-MODE FILTERS FROM TRANSIMPEDANCE OPAMPS

Although a commercially available transimpedance opamp is suited for implementing high-performance biquad in the current mode, this article aims to contribute to the broader and more practical applications of these circuits, particularly where a regular opamp is unsuitable. Its parasitic intrinsic qualities are presented. Initially, it was recommended that more modes be distinguished in which the given circuit can operate, namely the voltage mode and the current mode. Focus was also made on hybrid modes, specifically the voltage-current mode or the current-voltage mode.
