Abstract :
Mobile cellular radio systems built for the new GSM digital specification, or for the lower cost analogue networks, rely heavily on advanced semiconductor technologies for realisation of the complex VLSI digital and low-power analogue integrated circuits used within them. Mixed signal ASICs using 3-micron and 1.2-micron analogue CMOS processes have been designed for mobile telephone control functions, speech and data processing, speech scrambling, signal companding, modulation/demodulation, and data conversion. Innovative design has ensured that minimum power consumption and high levels of component integration are achieved
