The wireless communication systems have become animportant part of our lives. The everincreasing demand toward lower cost makes the taskof the wireless communication circuitdesigner more and more challenging. This demandtranslates into the specifications as theneed of designing the circuits with lower powerconsumption, with smaller die area but without anycompromise from the final goal of higherperformance. The circuit design for wirelesstransceiver front-ends hasan additional complexity due to the high frequencyof operation involved. This book includesdiscussions on the fully-integratedVCOs, prescalersand Q-enhanced LC bandpassfilters on silicon within the framework of RFintegrated circuit design forwireless communication transceivers. The advantagesand shortcomings of the circuits are presentedtogether with the associated design trade-offs,based on simplified noise andnonlinearity analyses. Measurement results of thedesigned and implemented LC VCOs, a dual-modulusprescaler and a Q-enhanced LC bandpass filter areprovided. This book will be of interest to analogcircuit designers and researchers in the field of RFIC design.
