A transistor-only power-efficient high-frequency voltage-mode stimulator for a multichannel system

摘要

This paper proposes a fully implantable high-frequency switched-mode neural stimulator. The main circuit consists of 2N transistors for an N-electrode system in which all channels can be stimulated concurrently and independently. System simulations show that power efficiencies of 80% or higher are feasible over the full output range.
