“…Therefore, pseudo-differential frequency filters [24] - [32] were proposed as a possible trade-off between fully-differential and single-ended filters. They provide a simpler structure as single-ended circuits and provide similar features to fully-differential circuits.…”

In the paper, the theory of systematic design frequency filters is described. The result is a fourth-order pseudo-differential frequency filter operating in the voltagemode and implemented as a cascade connection of two basic second-order blocks. The filter is able to realize the low-pass filtering functions. The basic block employs three active elements and four passive elements. The filter is characterized by a minimum number of passive elements and high output impedance. Filter analysis examines the magnitude, phase, common-mode rejection ratio signal, and behavior of filters while reducing the recommended voltage. The proper functionality of the filter is verified by simulations and experimental measurements for two different interconnections.
