Abstract::
Recent popularity of smart phones, netbooks, and other mobile broadband devices
has vindicated third generation (3G) cellular communication systems as an
enabling technology and has given fresh impetus to the development of fourth
generation (4G) systems. Considering however the predominance of second
generation (2G) systems, a complete transition to the next generation of
wireless systems is not feasible. The success of new wireless standards is
therefore contingent on highly integrated, multi-mode radios. Low-power
multi-mode ADCs have consequently become a key component in wireless receiver
design. The most promising multi-mode ADC architecture is delta-sigma (∆Σ)
modulation which forms the subject of this thesis. ∆Σ modulator
techniques are presented in this thesis which are demonstrated with a 2-2
cascaded and a third-order single-loop multi-mode ∆Σ modulator
prototype implemented in 0.13μm CMOS,
covering bandwidths up to 10MHz and 20 MHz, respectively, to support
GSM/EDGEup-to-IMT-Advanced multi-standard scenarios.
