Abstract
A novel poly-phase switched-capacitor (SC) circuit architecture for IIR Hilbert transformation is proposed for the application of wide-band 90° phase shifting. The circuit employs fewer active elements and has better performance than the traditional two-phase circuit. SWITCAP2 simulation results, phase sensitivities to capacitance mismatches and other non-ideal effects are discussed
