The key to propagation delay in bipolar logic family is to prevent the transistors in a gate from ___________
A. Fan-in
B. Fan-out
C. Saturation
D. Cut-off
Answer:C
The key to propagation delay in bipolar logic family is to prevent the transistors in a gate from ___________
A. Fan-in B. Fan-out C. Saturation D. Cut-off
Explanation: The key to propagation delay in bipolar logic family is to prevent the transistors in a gate from saturation. In Saturation mode, the transistor is in “ON”mode, where it seems like a short circuit between collector and emitter.
