14.9 ps/2.2 mW charge-buffered active-pull-down ECL circuit

An ECL circuit with a charge-buffered active-pull-down emitter-follower stage is described. Implemented in a 0-8 /an double-poly trench-isolated selfaligned bipolar process, unloaded gate delays of 14.9ps/2.2mW, 20.7ps/1.2mW, and 24.5ps/0.77mW have been achieved. © 1992, The Institution of Electrical Engineers.
