WebEmitter-Coupled Logic (ECL): The ECL family is the fastest logic family in the group of bipolar logic families. The characteristic features that give this logic family its high speed or short propagation delay are outlined as follows: It is a nonsaturating logic. WebJul 1, 1996 · An emitter coupled logic gate (300) avoids the use of stacked transistors by utilizing a single-ended bias input and positive feedback (320) between first and second transistors (304, 306) to achieve an inverter function. The inverter (300) can also be configured as an OR gate (500) by adding a third transistor biased by second single …
