The present invention relates to CML(Current Mode Logic)-type input driving method and tunneling diode logic using MOBILE(Monostable Nistable transition Logic Element) configuration, as kinds of very high-speed digital logic circuits. The objectives of the present invention are to improve the disadvantage of MOBILE circuit configuration that is an existing tunneling diode logic, and at the same time provide new MOBILE based logic functions. Wherein, the difficulty for input voltage adjustment is resolved by replacing the input part with a CML input driving gate, and speed problem due to transistor is resolved. Moreover, a plurality of logic functions such as inverted return-to-zero D flip-flop, non-inverted return-to-zero D flip-flop, return-to-zero OR gate, return-to-zero D flip-flop generating differential output, and optical flip-flop are implemented.
A tunneling diode logic circuit, in MOBILE(Monostable Bistable Transition Logic Element) circuit including input driving circuit, using CML-type input driving circuit configuration and MOBILE including said input driving circuit configured with CML(Current Mode Logic)-type gate, and current source in which maximum current value getting out from output to said input driving circuit in accordance with input voltage is configured to be limited with constant value.
