An Analog Array Approach to Variable Topology Filters for Multi-mode Receivers

摘要

Recent development of the communication industry imposes new challenges on the design of wireless terminals. The ever increasing diversification of services has led to more and more complicated equipments, supporting extended functionality. The digital section of wireless terminals greatly benefits of the advantages offered by the rapid advancement of semiconductor technologies. Miniaturization allowed an increasing complexity and higher operating frequencies, leading to better performance and more integrated functionality of digital circuits. Therefore, digital processors and their driving software can relatively easily cope with the demands of modern multi-mode wireless technologies [1].
