ABSTRACT:
A BICMOS input stage includes a level shifting stage (35) and a level converter/buffer circuit (60). The input stage receives a single-ended GTL level input signal and a reference voltage, and in response, provides differential BICMOS level output signals. The input stage operates over a wide range of values for the reference voltage, does not require the generation of complex bias voltages, and provides well controlled output signals.
