Abstract :
An integrated circuit for a GSM system is described which acts as a raised cosine shaper for the ramp up and ramp down of a transmitted burst. By use of this shaper, GSM specifications for switching transient spectrum and power level versus time are fully met. The circuit which includes two 8 bit D/A converters, was fabricated using a 2 ¿m CMOS process and its size is about 3*2.8 mm2.
