A three-phase complex filter for a balanced three-phase analog signal processing is proposed. The proposed three-phase active-RC Tow-Thomas biquad complex filter can reduce total resistance by 10 percent, total capacitance by 25 percent, and power consumption by 22 percent compared to a conventional fully differential quadrature complex one.
