초록

본 논문에서는 능동소자를 포함하는 마이크로파 회로의 주파수 특성을 해석하기 위하여 확장된 유한차분 시간영역법 (FDTD) 을 이용했다. R, L, C와 같은 집중소자가 전송선로에 삽입된 FDTD 집중소자 모델링을 통해 하이브리드 회로 해석에 대한 기초 연구를 수행하였고, 네트워크 모델링을 이용하여 기생 커패시턴스와 인덕턴스의 값을 추출함으로써 보다 정확한 기생, 방사, 결합까지 고려하는 FDTD만의 고유한 주파수 응답을 확인할 수 있었다. 또한 FDTD를 이용하여 모델링된 다이오드를 사용한 평형 혼합기를 설계하여 상용 회로 시뮬레이터보다 정확하고 실제적인 회로의 주파수 응답을 획득하였다.

In this paper, the extended FDTD is used for the analysis of microwave circuits including active elements. Lumped elements such as R, L, C which are inserted into a microstrip line are analyzed with the FDTD lumped element modeling. Parasitic capacitance and inductance could be obtained using network modeling and so it is sure that FDTD lumped element modeling makes it possible to get more accurate data which include parasite components. Moreover, a balanced mixer using two diodes that are modeled by an extended FDTD is designed and the more exact characteristic of the mixer is acquired than in current circuit simulator.
