Abstract

Method how to design fully-differential nth-order synthetic elements that are used to design nth-order F-D filter is presented in this contribution. Initial single-ended synthetic cell is included. Simple balanced-output current active elements are used in the case of the single-ended variant, equivalent fully-differential elements are implemented in the case of fully differential variant. 4th-order low-pass and high-pass responses are shown as an example of particular solution. Simulation results obtained with 3rd-order models of active elements are included. Features of fully-differential and single-ended variant are compared in the worst-case analysis.
