Abstract :
A new pole-zero pairing and ordering strategy which can provide the minimum total capacitance in cascaded biquad switched-capacitor (SC) filters is proposed. Design examples for several kinds of SC filters are demonstrated. The proposed conditions can limit pairing and ordering assignments, by which the total capacitance is concentrated within 5% over the minimum value
