本文章主要在設計各種不同架構的混波器，以達到微小化的目的。首先我們提出一個新的自振式混波器的架構，是利用了雙平衡式吉爾伯混波器結合NMOS壓控振盪器，來達到減少電路面積的目的。
接下來我們提出一個採用電阻性的混波器，來設計一個鏡頻拒斥混波器，利用此種架構結合集總式元件耦合器的設計，可以達到高鏡頻拒斥、高隔離度、低功率損耗、微小化的特性。

This thesis focuses on different structures mixer designs for minimizing the circuit. We propose a new structure Self-Oscillator Mixer at first. We use a double-balanced Gilbert cell mixers to combine NMOS voltage-controlled oscillator for minimizing the circuit.
And then we propose to use a resistance mixer, to design a image-rejection mixer. We have obtained a well-designed image rejection mixer with low power, miniature and excellent isolation.
