摘要:
An intregrated circuit structure is disclosed in which a pair of complementary lateral space charge limited transis tors are formed together with at least one Schottky diode to create a logic gate. The structure includes a semiconductor substrate, a first and a second region of N conductivity type spaced apart in the substrate, a third and a fourth region of P conductivity type, the third region separating the first region from the second region, and the second region separating the third region from the fourth region. The first region has a graduated impurity concentration which is less than 10¹⁸ atoms per cubic centimeter at the surface and at least 10¹⁸ atoms per cubic centimeter at a selected depth below the surface of the substrate.

摘要:
An 1 2 L logic circuit provided with a logic section (126) which includes at least one 1 2 L unit circuit (120) formed of a transistor for injector (122) and a driving transistor (124). The 1 2 L logic circuit is further provided with a supply circuit for supplying the 1 2 L unit circuit with an injector current corresponding to a control signal. The supply circuit is formed of a first circuit (132) for steadily supplying the 1 2 L unit circuit (120) with a predetermined injector current, and a second circuit (136) for supplying the I 2 L unit circuit (120) with another injector current in accordance with the control signal, the first and second circuits (132,136) being connected in parallel with each other.
摘要:
Bei einer Grundschaltung einer integrierten Transistor-Logik ist an die Basis eines ersten, normal betriebenen Transistors (T5) ein ständig Strom liefernder Injektor angefügt. In Abhängigkeit von einem zusätzlich der Basis zugeführten logischen Eingangssignal wird der Strom entweder in die Basis injiziert, so daß der Transistor (T5) leitend wird, oder von der Basis abgeleitet, so daß der Transistor (T5) gesperrt wird. Die den Kollektor und die die Basis des ersten Transistors (T5) bildenden Halbleiterzonen stellen gleichzeitig die Kollektoren und Basen von zusätzlichen zweiten Transistoren (T2, T3, T4) dar, deren Emitter die Ausgänge der logischen Grundschaltung bilden. Die im Schaltzustand mit leitendem erstem Transistor (T5) ebenfalls leitenden zweiten Transistoren (T2, T3, T4) werden dabei in inverser Richtung betrieben. Durch diese Anordnung wird in erster Linie gewährleistet, daß auch bei Auftreten von Kurzschlüssen oder Leckstromwegen durch die Basiszonen der Transistoren hindurch die Funktionstüchtigkeit der Schaltung in den meisten Fällen erhalten bleibt.
摘要:
A bias circuit (20) that is comprised of negative feedback loop (28-36) and including a two collector I²L gate (26) having one collector returned to the input of the gate to force a reference current into the other of the two collectors of the gates, such that the current at the collector of the injector of the gate is matched to the reference current. The feedback loop further includes a current source (30) for sourcing the reference current and a pair of cascoded emitter follower transistors (32, 36) coupled between the current source and the injector input of the gate such that the feedback loop will regulate the current through the injector to be equal to the reference current. The injector input of the gate of the feedback loop can be coupled to the injector inputs of similar I²L gates to be biased therefrom such that the injector currents are well controlled.
