耦合電感壓控振盪器與空隙濾波放大器

Abstract

本論文實作部分包含壓控振盪器與功率放大器的設計。我們利用GCT 2.0 um InGap/GaAs HBT之製程，實現了頻率6.2GHz的耦合電感差動相位壓控振盪器電路以及頻率5.5GHz的耦合電感正交相位壓控振盪器電路。壓振控盪器採用Board level的方式量測，以避免電源供應器影響電路特性。6.2GHz的耦合電感差動相位壓控振盪器電路在6V的操作電壓之下，擁有-110.22dBc/Hz@1MHz的相位雜訊、-8.2 dBm的輸出功率、200MHz的可調範圍。而5.5GHz的耦合電感正交相位壓控振盪器電路在4V的操作電壓之下，擁有-108.92dBc/Hz@1MHz的相位雜訊、-3.5 dBm的輸出功率、120MHz的可調範圍。而空隙濾波放大器方面，我們完成阻抗轉換濾波器的設計流程，並利用WIN 0.15 um pHemt之製程，模擬以及實現60GHz的微帶線式與平面波導式空隙濾波放大器電路，預計將利用NDL高頻量測實驗室提供的On-wafer量測完成實作之量測。

This thesis presents the design of Voltage Control Voltage and Power Amplifier. First, we use GCT 2.0 um InGap/GaAs HBT process to implement 6.2GHz Coupled Inductor Differential Phase Voltage Control Oscillator and 5.5GHz Coupled Inductor Quadrature Phase Voltage Control Oscillator. The supply voltage of 6.2GHz DVCO is 6V and the phase noise is -110.22dBc/Hz@1MHz, the output power is -8.2 dBm and the tuning range is 200MHz. The supply voltage of 5.5GHz QVCO is 4V and the phase noise is -108.92dBc/Hz@1MHz, the output power is -3.5 dBm and the tuning range is 120MHz. We measure VCO circuit on board level to avoid the noise of power supply. We complete the design flow of impedance transform filter and use WIN 0.15 um pHemt process to simulate and implement 60GHz microstrip type Gap Coupled Filter Amplifier and 60GHz coplanar waveguide type Gap Coupled Filter Amplifier. We will measure it at NDL.
