Hysteresis turn-on-off voltages for a neural-type cell

Bounds on the range of input voltages which lead to hysteresis in a neural-type cell are presented. These are important to the field of neural-type networks which operate on pulses, as do biological ones, since the presence of hysteresis allows for coding of the pulses. Since design equations have not been readily available for NTCs (neural-type cells), the authors formulate equations for V_1low and V_1high which make certain in terms of circuit design parameters. With the voltages determined, they are in a better position to make engineering designs of pulse coded neural-type networks
