Design of ECL Integrated Circuits with High-Information-Density

Starting from the viewpoint that the information processed by integrated circuits can be increased by means of the multivalued logic, this paper studies the ternary ECL high-speed integrated circuits. The basic operations which conform with the action principle of bipolar transistors are proposed, and the relevant properties to these operations are discussed. Based on the above discussion, the theory of differential current switches is established and used to design some basic ternary ECL circuits. The computer simulations by SPICE 2G5 program show that these circuits have correct logic functions and ideal static and transient characteristics.
