Abstract

This paper presents the amplifier and stimulator circuits, as well as 50-Omega antenna driver, that augment a multichannel, wireless sensor interface platform IC for use in neurodynamic studies of a sea animal, Aplysia Californica. The prototype chip, including the platform and 2-channel neurodynamic interface circuits, has been fabricated in a 0.5-mum CMOS process, occupies an active area of just 0.7 mm² and consumes 3.56 mW. This would allow 120 hours of recording using 160mAh lithium ion battery. Test results of the interface circuits are presented and exhibit the desired performance
