鼠徑分合波吉伯特混頻器及次諧波混頻器設計

Abstract

本篇論文主要研究應用在三種射頻積體電路系統中的混頻器。第一，結合鼠徑分合波器和吉伯特混頻器達到寬頻收發的功能；第二，使用次諧波混頻器解決直接轉換系統的自我混頻問題；第三，利用複數混頻器解決低中頻系統的邊頻帶問題。除此之外，也對變壓器參數萃取的方法做分析，並整理一系列的變壓器參數。

In this thesis, we focus on the mixers applied in three ratio-frequency integrated circuit systems. First, rat-race hybrid and Gilbert mixer are combined into wideband circuit. Second, sub-harmonic mixers are designed in order to prevent the self-mixing problem in the direct-conversion system. Third, complex mixers are designed to reject the sideband signal in the low-IF system. Besides, we analyze the methods of extracting transformer parameters. We also arrange the transformer parameters provided by few technology processes.
