Abstract
An CMOS ECL output buffer has a CMOS differential amplifier. A CMOS reference circuit supplies a reference to a reference input of the CMOS differential amplifier. The reference has a high-state value suitable for use by ECL. A CMOS feedback circuit couples a buffer output as negative feedback to a feedback input of the CMOS differential amplifier. A CMOS output circuit supplies an output of the CMOS differential amplifier as the buffer output in response to an input. The buffer output is provided to the ECL. Accordingly, the buffer output is low when the input is low, and the buffer output has the high-state value when the input is high.
