Abstract:
A flip-flop circuit comprising:a series circuit which has a first negative differential resistance element and a second negative differential resistance element in such a configuration that one end of said first negative differential resistance element and one end of said second negative differential resistance element are interconnected at a common series connection point, that said second negative differential resistance element has a control terminal for controlling a value of an element current, and that said series connection point acts as an output terminal;clock supplying circuit for supplying a clock signal as an operating power supply for said series circuit;a latch circuit;a transfer gate which is disposed between an output terminal of said series circuit and said latch circuit and also which is turned ON and OFF by said clock signal; andan inverter circuit which is connected to said latch circuit;wherein an input signal is applied to said control terminal of said second negative differential resistance element, while an output of said inverter circuit is placed as an output signal.
