Abstract
Due to the increasing demand of higher data rate of the modern communication system, wireless communication system in millimeter-wave has become an important topic of interest. Recently, due to the rapid growth of the foundry process, it’s an essential topic to utilize sub-micron process to realize the high frequency essential element of the wireless communication system. Complementary metal-oxide-silicon field-effect transistors (CMOS) is the most attractive process because of its advantages as low cost and high integrity. The goal of the thesis is to utilize 65-nm CMOS process to design and realize the two essential elements of the wireless communication system, low noise amplifier and voltage control oscillator. Firstly, the basic of the wireless communication system is introduced. Secondly, the basic principle and circuit design of each essential element are introduced. The thesis proposes a low noise amplifier and a voltage control oscillator as the structure and design method. The first circuit utilizes TSMC 65-nm CMOS process to realize a low noise amplifier in 68-75 GHz, with a gain of 17 dB, and a noise figure of 7.4 dB. The second circuit also utilizes TSMC 65-nm CMOS process to realize a voltage control oscillator. In order to reach a better phase noise performance, conventional LC resonator is transformed to improve its quality factor. An oscillator, operating at 55.6 GHz, with a tuning range of 2%, is realized. Under 5 mW DC power consumption, it reaches a phase noise performance as -97 dBc/Hz at 1-MHz offset.
