應用多重耦合傳輸線原理求算射頻積體電路矩形螺旋電感

Abstract

在本篇論文中，利用多重耦合傳輸線理論分析射頻積體電路電感。配合商用軟體，如IE3D、FHSS或是MWO模擬多條耦合傳輸線之響應，再利用多重傳輸線理論萃取傳輸線R、L、G、C矩陣參數。根據多重耦合傳輸線的架構，將射頻積體電路矩形螺旋電感分解成多重耦合微帶線的組合。最後再利用HSPICE模擬等效電路以實現整體電感的電感值與Q值響應。

The multiple coupled transmission line theory is incorporated into analysis for RFIC inductors. Many commercial software packages, such as IE3D and MWO, can be used to simulate frequency response of a section of multiple coupled lines and to extract the transmission line parameters such as RLGC matrices from the frequency response of the multiple coupled lines in term of impedance and admittance matrices. Based on multiple coupled transmission line structure, a spiral inductor is decomposed into many sections of coupled microstrip line in a cascade. Finally, HSPICE is employed to simulate the frequency response of inductance and Q factor of the spiral inductor.
