Before revision:  In this paper, we present a moment matching method based on the extended Krylov subspace combined with the superposition property that can handle large input models and generate more accurate and efficient reduced-order models for circuit simulation methods.
After revision:  In this paper, we present a moment matching method based on the extended Krylov subspace combined with the superposition property in order to deal with many terminals. The proposed method can handle large-scale regular and singular circuits and generate accurate and efficient reduced-order models for circuit simulation methods.
