Synthesis of a Third-order Complex Coefficient RⁱCR Filter Using Small Number of Grounded Imaginary Resistors

Abstract

In this paper, a third-order complex RⁱCR filter using small number of grounded imaginary resistors is proposed. The proposed complex RⁱCR filter can be obtained by adopting the lowpass-highpass transformation and an equivalent transformation for the conventional complex RⁱCR filter including a floating type imaginary resistor. The validity of the proposed method is confirmed through experiment.
