An adjustable threshold MOSFET

A circuit which is equivalent to a voltage adjustable threshold MOSFET is presented. This adjustable threshold MOSFET uses the voltage adder from a neural arithmetic unit which is based on the describing equations of the neural chemical pools that occur in biological neurons. The threshold voltage of this adjustable threshold MOSFET is linearly modulated by an external control voltage. The circuits used here are all composed of MOS transistors and no resistor is used to convert current to voltage. Thus, these circuits will only occupy a small die area and are very suitable for VLSI realizations.<
