Abstract

For high frequency microstrip line modelling, a fast inductance extraction technique using an adaptive PEEC(partial element equivalent circuit) grid is proposed. The grid refinement technique is based on the current distribution depend on the excitation frequencies and the geometry of the microstrip lines. The adaptive ids are refined mainly in the area where heavy currents reside. This technique is applied to the inductance extraction of the microstrip lines. The results show fast convergence, and this adaptive technique is efficient to reduce computing time and the number of grids.

고주파용 마이크로스트립 선로의 모델링에 필수적인 인덕턴스의 빠른 추출을 위해서 고속화 알고리즘(fast mutilpole method)과 결합된 적응 PEEC 격자분할법(adaptive PEEC grid refinement algorithm)을 제안하였다. 격자의 세분화는 마이크로스트립 선로의 구조와 사용주파수에 따른 전류분포에 적합하도록 이루어졌는데, 이 적응 격자는 주로 전류분포가 높은 영역에서 더 세분화된다. 이 기법을 이용하여 마이크로스트립 선로의 인덕턴스를 구하였고, 계산결과는 빠르게 수렴하여 계산시간과 격자 수를 줄이는데 효율적임을 보였다.
