WebThe Answer: Because the CVD is a model simplified and does not account for the slope of the exponential i-v characteristic in forward bias. The Problem: The CVD model is not good enough to account for how the diode react s to small variations in the circuit, but the exponential model is too complicated to use for circuit analysis. http://ittc.ku.edu/~jstiles/312/handouts/Small%20Signal%20Analysis.pdf clemson vs cincinnati football https://skdesignconsultant.com
