Abstract

Abstract Translated from German ECL-kompatible Eingangs-/Ausgangsschaltungen in CMOS-Technik, die sehr enge ECL-Pegelanforderungen erfüllen und von Tempera­tur- und Feldeffekttransistorparameterschwankungen möglichst unabhängig sind. Dies wird erreicht durch eine Regelschaltung für die Referenzströme (IREFO1, IREFO2 ... IREFOn, IREFOn+1) der Stromspiegelschaltungen, bestehend aus einer Sensorstufe (S), einem Komparator (K), einem Tiefpaß (T) und einer Refe­renzstromquelle (IREFQ), sowie dem Einsatz von Stromspiegel­schaltungen in den Treiberstufen (TR1, TR2,...TRn) und der Sensorstufe (S). ECL-compatible input / output circuits in CMOS technology that meet very tight ECL level requirements and are as independent as possible from temperature and field-effect transistor parameter fluctuations. This is achieved by a control circuit for the reference currents (IREFO1, IREFO2 ... IREFOn, IREFOn + 1) of the current mirror circuits, consisting of a sensor stage (S), a comparator (K), a low-pass filter (T) and a reference current source (IREFQ) , as well as the use of current mirror circuits in the driver stages (TR1, TR2, ... TRn) and the sensor stage (S).
