Questions tagged [rise-time]
Anything related to the rise time of a signal. The rise time is a parameter used to characterize abrupt transitions in a signal waveform. It is usually defined as the time needed by the signal to go from the 10% to the 90% of the level it attains at the end of the transition.

What rise time should pulse have to have desired pulse width [closed]
I have a question regarding my high speed laser driver. I want to have 10ns width pulse. What rise/fall time I would need to have that I can say I still have 10ns pulse. Is there any percentage that ...

Minimizing pulled open collector output rise time on 74LS09
I have a circuit that calls for one open collector buffer for driving a shared line (/WAIT via Zilog Z80) and one typical AND gate. I've consolidated these into a single 74LS09 open collector quad 2-...

How to calculate the rise time?
The figure shows a modification, from state A to state B, carried out on the cell at the output of circuit (X).
In both cases, the voltage at point A is the same. The transistors M1 and M2 keep the ...

Can I calculate minimum rise time of a transmission line if I know the length and the loss tangent?
Overview: I am trying to work out if it's possible to transmit my 1.2Gbps MIPI data down a 600mm long flexible PCB strip. Assuming I have the impedance correct, will the signal still be degraded by ...

CMOS inverter in series
I have the circuit below.
Now my question is: why the rise time and fall time measured on Vout are the same as in a circuit using only one inverter gate?
I know the propagation delay is the sum of ...
