dc.description.abstract | This paper presents innovative architectures of hybrid Continuous-Time/Discrete-Time (CT/DT) cascade ΣΔ Modulators
(ΣΔMs) made up of a front-end CT stage and a back-end DT stage. In addition to increasing the digitized signal bandwidth
as compared to conventional ΣΔMs, the proposed topologies take advantage of the CT nature of the front-end ΣΔM stage,
by embedding anti-aliasing filtering as well as their suitability to operate up to the GHz range. Moreover, the presented
modulators include multi-bit quantization and Unity Signal Transfer Function (USTF) in both stages to reduce the integrator
output swings, and programmable resonation to optimally distribute the zeroes of the overall Noise Transfer Function
(NTF), such that the in-band quantization noise is minimized for each operation mode. Both local and inter-stage
(global) based resonation architectures are synthesized and compared in terms of their circuit complexity, resolution-bandwidth
programmability and robustness with respect to circuit non-ideal effects. The combination of all mentioned characteristics
results in novel hybrid ΣΔMs, very suited for the implementation of adaptive/reconfigurable Analog-to-Digital
Converters (ADCs) intended for the 4th Generation (4G) of wireless telecom systems. | es |
