| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 96 === In this thesis, we focus on two topics of Radio Frequency Integrated Circuits. The first is Marchand baluns and combination of Marchand baluns and active mixers. The second is signal generation by frequency dividers and oscillators.
We implement different type Marchand baluns by using TSMC 0.35μm CMOS technology and TSMC 0.18μm CMOS technology. Then Marchand baluns are integrated into active micro-mixers as LO input element, and it is demonstrated in TSMC 0.35μm SiGe BiCMOS technology process.
Conventional analog and digital frequency dividers are discussed in this thesis. We use TSMC 0.35μm SiGe BiCMOS technology process to implement truly 50% duty cycle divide-by-5 digital frequency dividers. Analog frequency dividers are more adaptable for high speed operation than digital ones, and they are implemented in high cut-off frequency Win 0.15μm HEMT technology process. In Oscillator circuits, we utilize trifilar to couple output signals. Direct coupling and series coupling by transistors both can generate quadrature signals. Finally, Quadrature Oscillators are implemented in TSMC 0.18μm CMOS technology process and TSMC 0.13μm CMOS technology process.
