Abstract
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.
