應用於超寬頻3.1~10.6GHz的多段式電感之電感電容調整式電壓控制振盪器

Abstract

本論文研製一個應用於超寬頻3.1-10.6 GHZ的電壓控制振盪器，此設計主要在於同一個單位面積中藉由改變不同的感值，讓產生的振盪頻率得以改變並同時能夠滿足於超寬頻網路的實體需求。此設計是利用模擬設計協助工具，經由交叉驗証、模擬得到一個可靠度高的模組。在這個單位面積中共有四組感值，由外部的控制電路，讓這樣的總面積晶片得以分別振盪在四種不同的共振頻率;也又能補足超寬頻3.1-10.6 GHz的頻帶需求。

This design is a voltage controlled oscillator applied for Ultra Wideband 3.1-10.6 GHz. Its key component is a switched inductor built in the same area of die. Switching the inductance, the LC tank resonate different resonating frequencies to afford the bandwidth request of UWB. The design utilizes some CAD to simulate the effect of inductor. After double check, this inductor model has high reliability to feed this entire design. There are four different kinds of inductance in this unit area switching per peripheral control signal. At the same area of die it can generate four different kinds of resonating frequencies and afford the bandwidth requests to UWB 3.1-10.6 GHz.
