A re-configurable, highly-integrated receiver architecture is described for use in 3rd-generation mobile handsets. It is intended for dual-mode UMTS and GSM operation but should be capable of operating in other modes such as CDMA1000. The receiver achieves its adaptability by using a single down-conversion approach to either a zero IF or a near-zero IF and then digitizing as much of the IF signal chain as possible. Notwithstanding its re-configurability, system simulations indicate that the receiver should achieve state-of-the-art performance.
