Design Challenges of Wireless Mobile Radios

This paper discusses the challenges in designing modern wireless systems with focus on wireless mobile devices. It reviews the radio architectures and the design challenges imposed by the low-power specifications, small size and low cost in mobile terminals. Finally, the reconfigurable analog-to-digital conversion architectures that could support the multi-standard radio requirements in mobile devices are discussed in the perspective of a low-power CMOS design.
