ABSTRACT:
ECL-compatible input/output circuits in CMOS technology which meet very strict ECL level demands and are as independent as possible of temperature and field effect transistor parameter fluctuations. This is achieved by a control circuit for reference currents of the current mirror circuits. The control circuit is composed of a sensor stage, of a comparator, of a low-pass filter and of a reference current source. Current mirror circuits are also utilized in the driver stages and in the sensor stage.
