Analysis of the Dynamic Oscillatory Process of a Neural-type Cell (NTC) and Its Input Voltage Bounds
Zhengqing Wu, R.W. Newcomb · 2020
A neural-type cell (NTC) is an electronic circuit that mimics the behavior of a neuron. This paper mainly focuses on one type of NTC. It oscillates to produce pulse-coded signals. A complete description of the NTC's oscillation is offered in this paper. The description takes the body effect into consideration, which was never included in previous research work. Moreover, before, it was noticed by researchers that the NTC was able to oscillate only when the input voltage is within a certain range. However, an explanation of the physical essence of the input bounds has yet to be found. To tackle this, this paper provides detailed analysis to the turn-on/off input voltages. Additionally, although there has been a method proposed to calculate the input voltage bounds of an older version of NTC, it was based on numerical approximation and thus lacked universality. In this paper, a new way of calculating the oscillation-supporting input range for the latest version of NTC, the all-MOS NTC, is put forward.
