Description
Summary:In this paper, new receiver concepts and CMOS circuits for future wireless communications standards are introduced. Tradeoffs between technology, performance and circuit choices of the RF front-end circuits are discussed. In particular, power consumption, noise figure and linearity trade-offs in low-noise amplifiers, mixers and oscillators are considered. The concepts derived are applied to a few classes of wireless communications standards that are broadband in nature at RF and/or require a broadband IF. Multi-mode, multi-band operation and adaptability as key requirements for future generation receivers are highlighted throughout the paper.
