Abstract :
This paper presents the first demonstration of a complete CMOS 90 nm digital RF signal generator for wireless communication systems including a BAW (Bulk Acoustic Wave) based filter. A 1-bit delta-sigma signal generator is assembled with a BAW band pass filter for the UMTS TX-band at 1.95 GHz. The system satisfies UMTS specifications for ACPR and spurious emissions as defined in the IST MOBILIS project. The CMOS and BAW chip sizes are respectively 3.2 mm2 and 4.7 mm2.
