Circuit techniques for wireless bioelectrical interfaces

Recent advances in integrated circuit technology scaling, analog circuitry, and wireless communication have created the possibility for complex low noise, low power wireless instrumentation to be deployed in previously impossible scenarios, particularly in the realm of wireless sensing for biology research and biomedical applications. The generation of portable, autonomous devices made possible by these improvements will allow, for example, unobtrusive long-term health monitoring by way of fully implantable clinical diagnostic systems. This paper presents some achievements made to this end, and describes the circuit design techniques and system architectures used to realize low power wireless bioelectrical interfaces.
