Abstract :
A new flexible stimulus generator intended for a miniaturized implantable visual prosthesis has been developed. The device is based on a finite state machine (FSM) and uses 15-bit command words to generate various types of stimuli. Amplitude, pulse duration and interphase duration are the main programmable parameters of each stimulus. In addition, 3 built-in basic shapes allow the generation of a wide range of biphasic stimuli needed for our application. The proposed generator has been synthesized with VHDL language through a BiCMOS 0.8 μ technology
