Driver slew rate control
WebNov 2, 2024 · Rise Time/Fall Time (a.k.a. Slew Rate) Rise and fall time is a great stepping stone from setup and hold, because it starts to probe into frequency effects that are more analog than digital. How do you measure rise and fall time? Why do you care about it? Is monotonicity of a rising edge a requirement? How do you measure rise and fall time?
