Abstract :
An on-line tuning system based on the master-slave technique is proposed in this paper. The system is realized by employing only Operational Transconductance Amplifiers (OTAs) for the realization of all stages. As a result, attractive offered benefits are the suitability of implementation of the resulted configurations in both integrated and discrete-component forms. In addition, an advantage of the introduced topology is the reduction of the influence of the dc offset terms which are critical about the performance of such systems. The validation of the proposed topology is achieved through simulation results.
