Neural Encoder Using “PN-Body Tied SOI-FET”

This study reports the potential of PN-Body tied silicon on insulator field-effect transistor (PNBT SOI-FET) as a neural encoder. When a suitable resistor was connected to the body terminal of the PNBT SOI-FET, the generation of spike signals was confirmed. It was also found that the spike frequency varied by changing the values of the body, gate, and drain voltages. This indicates that the spike frequency contains information on the change in voltage values, and the neural encoding can be reproduced.
