Circuit modeling of programmable logic gate based on controlled quenching of series-connected negative differential resistance devices

Logic synthesis and circuit modeling of programmable logic gate based on controlled quenching of series connected negative differential resistance (NDR) devices are presented. At the rising edge of a clocked supply voltage, the NDR devices are quenched in the ascending order of peak currents which can be reordered by the control gates and input gate biases, thus providing programmable logic functions.
