Abstract

Generalized voltage mode filters that employ two current feedback amplifiers are proposed in this paper. The new biquads are attractive because they offer improved gain sensitivities compared to single current feedback amplifier biquads. Also they do not employ the Z node and so a wide range range of commercial current feedback amplifiers can be used in their implementation. Theoretical results as well as experimental results are presented using AD844s in which the accessible Z node is not used.
