An improved ternary three-rail JK flip-flop design

On the issue of the special structure of multiple-valued trigger with multiple-rail-output, a synchronous edge-triggered improved ternary JK flip-flop with three-rail output structure is presented based on the negative differential resistance (NDR) characteristic and the literal operation as well as the module operation. The ternary NDR JK flip-flop could set the logic values of the output to realize `0', `1' and `2' which leads the circuit function more perfect and the structure more complete. The NDR JK flip-flop is simulated by using the MOS-NDR network, the results verify the correctness.
