dc.description.abstractThe proliferation of modern communication systems places stringent requirements on analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) to operate on wideband signals while being power and resource efficient. In this thesis, the utilization of delta-sigma modulators for wideband and multi-band applications in both the receiver and transmitter is addressed. The first model proposes a low-complexity frequency band decomposition-based parallel DSM ADC architecture which lowers the resource consumption considerably compared to the conventional QMF-FBD ADC and maintains an acceptable SNDR. An FPGA implementation and resource estimation of the proposed model was performed as a proof of concept. The second model presents a concurrent dual band DSM architecture for spectrum aggregation transmitter application and provides a comprehensive analysis of step-by-step design process. The quantization noise is shaped in this architecture enabling concurrent transmission of two signals with low in-band noise interference. Simulation was performed with two carrier frequency bands of LTE signals as proof of theory.en_US
