Abstract
A novel polyphase switched-capacitor (SC) implementation of IIR Hubert tran sformers is proposed. The circuit employs fewer op-amps and has better perf ormance than the traditional two-phase circuit. SWIT-CAP2 simulation result s and phase sensitivities to capacitance mismatches are provided.
