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
