The ECL circuits usually operates with __________
A. Negative voltage
B. Positive voltage
C. Grounded voltage
D. High Voltage
Answer:A
The ECL circuits usually operates with __________
A. Negative voltage B. Positive voltage C. Grounded voltage D. High Voltage
Explanation: The ECL circuits usually operate with negative power supplies (positive end of the supply is connected to ground), in comparison to other logic families in which negative end of the supply is grounded. It is done mainly to minimize the influence of the power supply variations on the logic levels as ECL is more sensitive to noise on the VCC and relatively immune to noise on VEE.
