We present an idea for a new real-time reconfigurable perceptron, also called, a threshold
element. The circuit example contain three inverters with shorted outputs. SPICE simulations
for a 0.6/spl mu/m CMOS implementation operating in the subthreshold region. are shown.
The threshold voltages of the active devices, seen from driving nodes, may be dynamically
changed by adjusting their substrate potentials. This enables a change of the threshold of
the perceptron circuit in real-time. In terms of Boolean logic the functionality may be changed …

We present an idea for a new real-time reconfigurable perceptron, also called, a threshold element. The circuit example contain three inverters with shorted outputs. SPICE simulations for a 0.6 /spl mu/m CMOS implementation operating in the subthreshold region. are shown. The threshold voltages of the active devices, seen from driving nodes, may be dynamically changed by adjusting their substrate potentials. This enables a change of the threshold of the perceptron circuit in real-time. In terms of Boolean logic the functionality may be changed between 3-input NOR, CARRY' for the FULL-ADDER function and 3-input NAND, in real-time.
