Abstract :
A modular 32-site wireless neural stimulation microsystem is described. Up to 64 modules (2 per chip) can operate in parallel, while receiving inductive power and data at 2.5Mb/s from a 5/10MHz FSK carrier. The 4.6x4.6mm2 chip, fabricated in a 5V, 1.5μm 2M2P CMOS process, generates up to 65.8kpulses/s. Each module dissipates 8.25mW.
