A New Perspective on ECL Circuits

In this paper, the complementary and selective characteristics of ECL (Emitter-Coupled Logic) circuit are fully taken advantage to implement various logic gates including MUX, XOR, AND, NAND, OR, and so on. From the analysis, we find that one ECL circuit can realize many relative logic functions, which is more flexible than CMOS logic. We conclude that if the characteristics of ECL circuit are fully taken advantages, the design of logic functions can be very easy.
