Deep submicron CMOS technologies enable sophisticated system-on-chip technologies, moving beyond traditional integration of digital functionality to include mixed-signal, RF, and power management capabilities. New levels of integration bring with them additional challenges that need to be addressed such as the cross-coupling of noise from digital switching circuits to sensitive analog/RF blocks, and the handling of high voltages by the PMU with decreasing maximum gate/drain-source voltages. This work describes SoC integration in local area wireless (e.g., Bluetooth) as well as in cellular applications (e.g., GSM).
