Open publisher page 0 citations

Abstract

The circuits, including 4 value TTL, NOR gate and NAND gate and AND OR NOT gate and five state gate, are designed by use of bipolar transistors. They have good I/O characteristics, great load capacity and robust noise immunity, and their noise margin may reach±0.6V. Especially, the circuits of NAND gate and AND OR NOT gate are totally made of NPN transistors; moreover, with structure, it is easy to make them into integrated circuis. The circuits introduced in this paper are very practical and can be used as the basic unit circuits of 4 value digital system, artificial neural network and fuzzy logical system.
