Abstract :
The design of composite opamp Wien-Bridge oscillators is systematically approached by using a general model including amplitude control issues. Two different design criteria are presented and their main features summarized. A general composite opamp topology from which a catalog of structures can be obtained in a systematic way is presented. Experimental data are included illustrating the performance of the proposed design criteria
