博士 === 國立中山大學 === 電機工程學系研究所 === 102 === Future wireless communication systems will be more focused on having high data rates or low-power consumption. This dissertation aims to investigate and implement wideband receiver radio-frequency (RF) front-end integrated circuits (ICs) and high energy-efficient RF receivers. Based on this aim, the dissertation includes three major topics. First of all, two novel wideband CMOS common-gate low-noise amplifiers (LNAs) are proposed. They use dual-feedback schemes to simultaneously achieve input and noise impedance matching. Moreover, using an on-chip transformer in these LNAs significantly enhances the bandwidth of the associated gain factors. Next, a flip-chip RF front-end module package which stacks a CMOS RF front-end IC above a glass integrated passive device substrate is studied. This package has not only high linearity and low noise figure over a specific wide frequency range, but also a miniature size. Finally, two frequency shift-keying (FSK) receivers with low complexity are presented. These receivers utilize an injection-locking technique to remove the widely used phase-locked loop in a local oscillator. Furthermore, combined with a self-oscillating mixer or a divide-by-2 frequency divider plus a subharmonic mixer, the presented FSK receivers achieve superior sensitivity with very low power consumption.
