Reconfigurable Receiver With Radio-Frequency Current-Mode Complex Signal Processing Supporting Carrier Aggregation PROJECT TITLE :Reconfigurable Receiver With Radio-Frequency Current-Mode Complex Signal Processing Supporting Carrier AggregationABSTRACT:A software-defined radio receiver that's suitable for intra-band carrier aggregation is demonstrated. The RF front-end frequency selectivity is enhanced by the mixture of the passive mixer and a proposed reconfigurable transimpedance amplifier. High order bandpass filtering function with frequency notches can be achieved at the front-finish. Current domain advanced Signal Processing is explored to pick and separate multiple channels concurrently. The receiver contains a selection of practical building blocks which will be connected in different ways in which to form various architectures. The fine-grained programmability of element parameters and reconfigurability of receiver schemes enable optimum performance under varying signal and blocker situations. A proof-of-concept CMOS chip fabricated during a 65 nm CMOS technology is presented that supports up to three-channel aggregation. The receiver operates at any frequency between 0.five to 3 GHz. The frequency separation between the concurrent RF channels will be tuned anywhere between zero to +one hundred MHz. The concurrent receiver scheme will additionally be explored to reject large close to-band blockers for prime dynamic vary. Did you like this research project?
