Question: a circuit board is being designed with amp 42 a...

Question details

A circuit board is being designed with &= 4.2. A trace for a slow, infrequently changing signal has a length of 25 cm. a. What risetime is needed for the trace to be considered distributed and not lumped? b. What knee frequency corresponds to the risetime you calculated in a? c. The signal has a risetime of 1 ns. One way to avoid signal integrity issues is to slow the signal down to the point where it is no longer distributed. What RC (that is, an RC time constant of what value) is needed to slow the signal down to the risetime you calculated in a? The load capacitance of the signal is 20 pF^ What value of resistor should be inserted onto the line to obtain the value of RC you calculated in c? d.
