Abstract

A GSM base-band transmitter with strong requirements for linearity, matching and power dissipation has been designed in Atmel CMOS 0.18um technology. This paper recalls the digital Gaussian Minimum Shift Keying (GMSK) modulation imposed by the ETSI standard and briefly considers the design and the physical implementation of the transmitter itself (IQDAC) into a noisy environment. A test-chip, including the entire GSM base-band (IQDAC and IQADC) and a digital GMSK modulator, is presented. Measurement results are summarized at the end for the transmit part.
