Michigan State University, East Lansing, MI 1 2 Deep-brain stimulation (DBS) has been proven as an effective therapy to alleviate Parkinson’s disease, tremor, and dystonia. Towards a less invasive headmounted DBS, we utilize an inductive transcutaneous link to provide sufficient power without size, lifetime, and discomfort of chest-mounted battery-powered traditional DBS. The next step is to adopt aggressive power-management schemes to further improve the DBS efficiency. Current-controlled stimulation (CCS) enables precise charge control and safe operation, but it has low power efficiency due to the dropout voltage across current sources [1,2]. Switchedcapacitor stimulation (SCS), proposed in [3], takes advantage of both high efficiency and safety using capacitor banks to transfer charge to the tissue, but it requires an efficient on-chip capacitor charging system, directly from the inductive link. We present an integrated wireless SCS system-on-a-chip with
