The speed of ______ circuits is limited by the tendency of common emitter circuits to go into saturation.
A. TTL
B. ECL
C. RTL
D. DTL
Answer:A
The speed of ______ circuits is limited by the tendency of common emitter circuits to go into saturation.
A. TTL B. ECL C. RTL D. DTL
Explanation: The speed of TTL circuits is limited by the tendency of common emitter circuits to go into saturation due to the injection of minority carriers into the collector region. Hence, it functions slowly compared to CMOS devices.
