Time delay of a gate is affected by the?

The time delay of a gate is affected by the following:

1. Intrinsic delay of the gate, i.e., delay due to internal load.
2. Fanout (load) dependent today. The Delay of a gate increases as its fanout (capacitive load in CMOS) increases.
3. Fanin dependent delay. Gates with high fan-in have a high delay.
4. Supply voltage fluctuations affect delay. Delay decreases with increase in supply voltage.
