Abstract

The Twente 128-fold 3-dimensional multi-micro electrode device for endoneural stimulation is controlled by a 4×4 mm CMOS gate array chip. The chip contains the electronic circuitry, i.e. eight 16-channel multiplexers, eight double current sources and six differential amplifiers. Control of the gate array circuitry by a PC is done by a PCI interface. We present (aspects of) the design and realization of the PCI interface, as well as the simulated and measured performance figures of the current sources and amplifiers
