Survey of wireless baseband SoC for biomedical application

Recent developments in biomedical sensors has led to wearable medical devices which made energy efficiency a prime factor to consider. Hardware accelerators offer signal-processing capability with energy consumption lower than general-purpose CPUs/DSPs. Hence, great interest has risen recently in dedicated biomedical systems on chips that target extremely low levels of power consumption. Many power reduction techniques have been used, such as: multiple supply voltages (voltage islands), power gating, clock gating and voltage scaling, these techniques provided means for optimum energy efficiency operation. This paper attempts to briefly review the current research in biomedical SoCs.
