Single Chip Cellular Radios for GSM, GPRS, EDGE

Nowadays CMOS Baseband-radios for GSM/GPRS application are running in high-volume production. The next step for higher integration is the integration of the Power-Management Unit (PMU) and extending the functionality towards EDGE capabilities. This extended integration promises lower production cost, easier board design and the highest flexibility in system optimization. In this paper we will present both features as highest integrated solutions for cellular phones.
