Summary

This paper introduces a new circuit-level idea for driving optrodes in an optical stimulation system. Trying to make the stimulation circuitry energy efficient, the proposed idea is based on the basic concept of adiabatic circuits. Based on the idea proposed in this paper, a prototype stimulation circuit was developed and tested. The optical stimulation back-end also includes a micro-fabricated optrode array, specifically designed, developed, and tested for multi-channel optical stimulation in a semi-implantable optogenetic system.
