Abstract
An ECL input circuit which receives an ECL input signal and which generates, in response to the input signal, a CMOS-compatible output signal. The input circuit includes a bipolar transistor, having its emitter region adapted to receive the ECL input signal, having its collector region coupled to a first current source, and having its base region connected to a second current source. The circuit further includes an output circuit which is coupled to the collector region of the bipolar transistor for providing the CMOS-compatible signal.
