    Abstract
    Design techniques and procedures to improve performances of radio-frequency and millimeter-wave front-end integrated circuits were developed. Power amplifiers for high data-rate wireless communication applications were designed using CMOS technology employing a novel device resizing and concurrent power-combining technique to implement a multi-mode operation. Comprehensive analysis on the efficiency degradation effect of multi-input-single-output combining transformers with idle input terminals was performed. The proposed discrete resizing and power-combining technique effectively enhanced the efficiency of a linear CMOS power amplifier at back-off power levels. In addition, a novel power-combining transformer that is suitable to generate multi-watt-level output power was proposed and implemented. Employing the proposed power-combining transformer, a high-power linear CMOS power amplifier was designed. Furthermore, receiver building blocks such as a low-noise amplifier, a down-conversion mixer, and a passive balun were implemented using SiGe technology for W-band applications.
