This paper presents a multi-standard reconfigurable sigma-delta modulator, which is able to support the predictable standards of fourth generation of mobile communication systems (4G). Furthermore, the proposed architecture halves the number of required analog-to-digital converters in parallel receivers, by processing concurrently two different signals. The major design issues are outlined and operation modes are detailed. A system-level simulation is performed to demonstrate the feasibility of the presented solution.
