Abstract
This paper describes the architecture for a CMOS polar modulator IC that supports AMPS, ANSI-136, GSM/GPRS, and EDGE in a single modulator. Extension to include UMTS has been prototyped. The paper includes design details and evaluation results. The architecture has a high digital content and is potentially suitable for integration into baseband ICs. Performance results for transmitters using this design are included.
