Digital Logic Families

What is Emitter Coupled Logic (ECL) Circuit?

What is Emitter Coupled Logic (ECL) Circuit? Emitter coupled logic (ECL) is the fastest of all logic families and, therefore, is employed in applications where very high speed is essential. High speeds have become possible in ECL because the transistors are used in differential amplifier configuration, in which they are never driven into saturation and …

What is a Digital Integrated Circuit?

What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip, which is very small piece of semiconductor material, miniature circuits are produced by using advanced photographic technique. The finished network is so small that microscope …
