Abstract
This paper describes a new integrated topology circuit for a waveform shaper which will be used inside a GSM system. The circuit generates a raised cosine shape output for the ramp up and ramp down of a transmitted burst. The circuit was realised using two 8-bit current-steering digital-to-analog converters. The measured results of the transient spectrum and the power level versus time show that the circuit fully meets GSM specifications
