Abstract

A pulse current generation circuit () for neural stimulation includes an analogue signal receiving device () for receiving an analogue signal; an analogue-to-digital converter () for converting the analogue signal into a digital control signal; a current signal controller () for producing, according to the digital control signal, pulse current parameters for generating bidirectional pulse current signals; and a current generator () for generating, according to the pulse current parameters, bidirectional pulse current signals for neural stimulation, and the current generator can generate pulse currents of different precisions according to the pulse current parameters. In addition, the present invention further relates to a charge compensation circuit, a charge compensation method, and an implantable electrical retina stimulator using the pulse current generation circuit or the charge compensation circuit.
