What is Emitter-Coupled Logic?

When multiple digital signals have to be combined, engineers use several types of logic gates. One of the most popular and widely used types of logic gates made of transistors is called the Emitter-Coupled Logic or ECL. It makes use of a transistor-based differential amplifier to amplify and combine digital signals. Usually, these circuits or gates, as they are commonly known, have multiple inputs and most are single output. Circuit design ensures that none of the transistors in the gate ever saturates Read more [...]
