1.65 Gb/s 60 mW 4:1 multiplexer and 1.8 Gb/s 80 mW 1:4 demultiplexer ICs using 2 V 3-level series-gating ECL circuits

The 1.65 Gb/s 60 mW 4:1 multiplexer and 1.8 Gb/s 80 mW 1:4 demultiplexer ICs in a 1.2 /spl mu/m, 15 GHz bipolar process operate with a -2 V single power supply, and exhibit the lowest power-delay products reported to date. Low dissipation results from ECL circuit techniques enabling three-level series gating with a 2 V supply.
