ECL-to-CMOS signal level converter

摘要

A signal level converter is disclosed, for converting a signal having a first logic voltage swing characteristic to a signal having a second voltage swing characteristic. The converter comprises a level converting section and a differential circuit coupled thereto. The level converting section converts the supplied signal at the first logic voltage swing to an intermediate signal at a logic voltage swing different from the first voltage swing. The differential circuit 3, being supplied with the intermediate signal, produces an output signal at the second voltage swing level that corresponds to the potential difference between a high and low potential power supplies.
