Abstract

This paper presents a design and simulation of proposed MASH (Multi-stAge noiSe sHaping) modulator which can be used for GSM applications. MASH technique is chosen for GSM system, since low settling time, spurious level and phase noise can be obtained by using this technique. The phase noise obtained with this modulator is 30 dB if compared with other modulating techniques. Matlab (R2013a) is used for simulation of 3rd order, 32-bit digital MASH modulator.
