Integrated circuit manufacturing and packaging are important issues in realization of advanced electron devices and solid-state circuits. In this paper we develop a minimal equivalent circuit extraction technique for the high-speed PCB circuit design. Different from the conventional one, the state-space equation is constructed based on the separate set of poles instead of the common set of poles. Illustrating example is performed to show the validity of the proposed method. The extracted equivalent circuit from the proposed method has circuit components two times fewer than those form the conventional one. Furthermore, the circuit extraction takes simulation time four times faster than that of the conventional one.
