Due to the gradual growth in the industry of medical devices especially in Implantable Medical Devices (IMD), the research in this area has grown in the past few years. A number of studies have demonstrated the potency of Deep Brain Stimulation (DBS) for dystonia, Parkinson’s disease etc. Therefore, DBS is now a significant option when medical therapy fails. This paper presents a sensing structure requiring minimal power consumption. While this paper focuses on the key sensing features it shows that the scaled silicon technologies coupled to the shorter interconnect, give significant advantage for resolution and power consumption of the initial sensing.
