Abstract

A very small (less than 1mm3) wireless implantable optogenetic stimulator is presented. The device is based on a novel CMOS-controlled optical power transfer platform suitable for very small electronic systems. The CMOS-integrated optical power receiver chip drives an InGaN LED with "charge and drive" scheme. An optogenetic stimulation capability with sufficient stimulation intensity was successfully demonstrated.
