Chapter 12

Future of RFDAC

Abstract

With the proliferation of wireless networks, there is a need for more compact, low-cost, power-efficient transceivers that are capable of supporting the comprehensive communication standards including GSM, WLAN, Bluetooth, GNSS, FM, and 4G of 3GPP cellular. To accommodate the ever-increasing appeal of higher data throughputs within the crowded frequency spectrum of 500 MHz to 6 GHz, these communication standards utilize extremely efficient complex-modulated baseband signals in which their related bandwidths can be as wide as 160 MHz. Moreover, due to the extreme cost pressures of consumer electronics, migration to a more advanced nanometer-scale CMOS process, which was primarily developed for fast and low-power ...
