Abstract
A polyphase switched-capacitor (SC) IIR Hubert transformer with reduced sen sitivity to finite opamp gain and bandwidth is proposed for high frequency applications. Low sensitivity is achieved by applying a predictive correlat ed-double-sampling (CDS) technique. Theoretical analysis and SWITCAP simula tion results are given.
