Abstract :
A wireless retinal implant with a low-power area-efficient stimulator chip features an ASK demodulator, single-ended-to-differential converter, low-power DLL and programmable current drivers. The chip dissipates 1.3mW from plusmn2.5V at a data rate of 100kb/s. The chip is powered and driven through a wireless inductive link separated by 15mm
