Abstract:
1. A MOBILE based D-type flip flop, comprising: negative differential resistance diodes receiving a common clock signal, and commonly biased negative differential resistance diodes respectively connected to said negative differential resistance diodes receiving the common clock signal, and transistors, wherein each collector of the transistors is respectively connected between one of said negative differential resistance diodes receiving the common clock signal and between one of said commonly biased negative differential resistance diodes, each emitter is connected to a common current source, and each base comprises an input port; and the flip-flop is configured to be operated in a Non-Return-to-Zero mode, in which each collector of said transistors is respectively connected to the base of a transistor for a SET/RESET latch circuit, and an output port is connected to the collector of said SET/RESET latch circuit.
