Abstract :
This paper deals with design issues related to the realization of wave active filters (WAF). Continuous-time current-mode implementation is considered and the basic building blocks are presented along with their sensitivity properties. A new optimization method of dynamic relations in WAF is derived and its application in practice is explained. Furthermore, the influence of parasitic elements of functional blocks used in WAF on transfer function is discussed. The introduced theory is thereafter utilized by way of a design example.
