Integrated JK-flipflop circuit including hot-electron transistors

摘要

An integrated JK-flipflop circuit comprises two cross-coupled inverters formed by a transistor and a resistor element connected in series therewith. Additional logic elements connect inputs of the flipflop to the cross-coupled inverters. It is a goal to provide the flipflop circuit on the smallest possible semiconductor area. This is achieved since the transistors of the inverters are designed as hot electron transistors, whereby each of these transistors is combined with one of the additional logic elements provided as a field effect transistor to form a common component which assumes two transistor functions but only requires the area of one field effect transistor.
