Abstract
The availability of millimeter-wave (mm-wave) communication systems is a key enabler in developing the fifth generation (5G) mobile networks that offer higher data throughput, lower network latency, and improved link robustness. Namely, they take advantage of mm-wave phased arrays to empower 5G communication systems that establish directional links with large bandwidths between the base station and user equipment. Despite this huge potential, mm-wave 5G has several natural disadvantages. The shorter wavelength of mm-wave signals results in lower penetrability, higher free-space path loss, and susceptibility to atmospheric attenuation, limiting network coverage. Additionally, 5G systems, offering high data throughput, require the use of complex modulation signals and, as such, need to handle large amplitude variations, complicating achieving high energy efficiency. Furthermore, their increased receiver noise lowers the sensitivity and link budget, while their use of Nanometer CMOS technology limits their transmit power and efficiency, impacting system reliability and thermalmanagement.
Unlike digital processors, whose performance and efficiency improve with semiconductor technology scaling, the performance of analog/RF front ends mainly relies on circuit and systemarchitecture innovations. Luckily, operating at mm-wave frequencies unlocks new opportunities, and an approach using those can exceed initial expectations. In this context, this dissertation introduces a series of innovative designs and techniques enhancing the performance and efficiency of power amplifiers (PAs) and transceivers for 5G mm-wave systems....
