碩士 === 長庚大學 === 電子工程學研究所 === 96 === This thesis presents the development of a 10~30GHz UWB voltage-controlled oscillator with standard CMOS technology. There are two groups of voltage-controlled oscillators (VCO) to be implemented. One is tuning range of around 7.5GHz to 10GHz and another is around 10GHz to 15GHz. Via the operation mechanism, we can switch on the special voltage-controlled oscillator. Then, it provides the frequency bandwidth of 20GHz. Furthermore, ADS (Advanced Design System) software is also used to design the whole circuit with the RF circuit simulation. The contents are divided into the following three parts. The first part presents the design of 15~20GHz UWB VCO. The simulation results are shown as follows: frequency range from 14.39 to 20.32GHz, phase noise from -100.6 to -109.5dBc/Hz@1MHz, output power from -1.1 to -5.2dBm and power dissipation of about 27.32mW. The second part is a design of 10~15GHz UWB VCO. The simulation result shows：frequency range from 10.26 to 14.41GHz, phase noise from -104 to -109.5dBc/Hz@1MHz, output power from -5.3 to -9.5dBm and power dissipation of around 29mW to 39.9mW. Finally, a 10~30 GHz integrated modules in advance is presented. The simulation result shows：frequency range from 10.38 to 29.49GHz, phase noise below -100dBc/Hz@1MHz, output power around -1.4 to -9.9dBm and power dissipation of around 68.72mW to 65.77mW (in total).
