What is the crucial function of Emitter-Coupled Logic (ECL) ?

a. Least Power Consumption

b. Saturated Logic Operation

c. Highest Packing Density

d. Maximum Power Consumption

ANSWER: Maximum Power Consumption

Explanation:

Transistors of ECL always operates in an active or cut-off regions & never goes in saturation region thereby eliminating the storage time.

ECL comprises difference amplifiers in addition to emitter followers. These emitter followers are utilized at the output of difference amplifiers for shifting the DC level by consuming maximum power at the requisite level.
