Abstract

Virtual electrode stimulation can provide extra selective spatial stimulation sites given if there is a highly configurable and controllable multi-channel stimulator system. The system has to have low latency between the loaded input data and output stimulation pulse, precise timing on simultaneously stimulation and an interface with external device such that a computer or FPGA can directly control each of the stimulation channels. This paper presents a general concept of virtual electrode stimulation and a multi-channel stimulation system that can support such operation. The system is designed in CMOS 0.35μm occupies 3.4×2.7mm² and consumes 2.3mW.
