摘要

本篇論文主要是研究應用於射頻積體電路上之被動電路，研究主題分成三個部分：
第一部份為應用於接收端超寬頻系統之3.1~10.6 GHz帶通濾波器。主要設計一個利用集總式元件之帶通濾波器，並搭配合成傳輸線，此濾波器具有極小的面積，通帶有良好的介入損失及截止帶具有三個傳輸零點的優點。我們利用0.18 mm CMOS製程設計了兩組帶通濾波器，第一組量測結果顯示3 dB頻寬是從3.1-11.1 GHz，低頻零點位於1.1 GHz,高頻兩個零點分別位於15 GHz and 27.6 GHz，最小插入損失為1.89dB和群速延遲為143±79.2 ps。第二組量測結果顯示3 dB頻寬是從3-12 GHz，低頻零點位於1.8 GHz,高頻兩個零點分別位於15.5 GHz and 19.7 GHz，最小插入損失為1.75dB和群速延遲為115±66.3 ps。
第二部份，我們提出一個應用於Ka-Band的帶通濾波器，利用0.13 mm CMOS製程設計，量測結果顯示3 dB頻寬是從25.3-38.7 GHz，最小插入損失為2.7 dB在31.9 GHz和群速延遲為31±9 ps。
第三部份，用MSL電感實現所提出的60-GHz 帶通濾波器的架構, 插入損失為2.55 dB在62.5 GHz和群速延遲為18.55±3.25 ps。

This thesis is mainly studied the passive circuit for RFIC applications. Study theme is divided into three parts：
The first part, 3.1 ~ 10.6 GHz band pass filter is designed for ultra-wideband (UWB). Mainly, a kind of band pass filter is designed by lumped device and implemented based on synthetic transmission lines (TLs). The filter has a compact area, low insertion loss in passband and there are three transmission zeros in the stopband. first work measured results show that the band pass filter has 3dB bandwidth range from 3.1 to 11.1 GHz,the low frequency transmission zero ?z1 = 1.1 GHz, the high frequency transmission zeros ??z2 = 15 GHz, and ??z3 = 27.6 GHz ,the minimum insertion loss of 1.89 dB, and group delay of 143±79.2 ps. and the second work measured results show that the band pass filter has 3dB bandwidth range from 3 to 12 GHz, the low frequency transmission zero ?z1 = 1.8 GHz, the high frequency transmission zeros ??z2 = 15.5 GHz, and ??z3 = 19.7 GHz ,the minimum insertion loss of 1.75 dB, and group delay of 115±66.3 ps.
In the second part, we propose a Ka-band band pass filter in standard 0.13 um CMOS technology, measured results show that the band pass filter has 3dB bandwidth range from 25.3 to 38.7 GHz, the minimum insertion loss of 2.7 dB, and group delay of 31±9 ps.
In the third part, A 60-GHz-band bandpass filter was implemented to demonstrate the proposed filter architecture and the developed MSL inductor structure. An insertion-loss of 2.55 dB was achieved at 62.5 GHz, and group delay of 18.55±3.25 ps.
