A retinal stimulator is an implantable device restoring vision by supplying a controlled, stimulating electrical signal to people blinded by retinal diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP). The resolution requirements of artificial retina systems become increasingly significant in their design as well as their(More)
The simulation and experimental study of current-mode DC-DC boost converter is presented in this paper The DC-DC converter is designed with a standard 0.35µm BiCMOS process. The off-chip LC filter is operated with the inductance of 1mH and capacitance of 100µF. The simulation results show the high performance DC-DC boost converter. The output(More)
