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.

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 ...

Generate ultrashort rise times with photoconductive switch or photodiode

I am trying to produce voltage pulses with very short rise time (<15 ps), medium width (20 ns) and amplitudes up to 15 V. As a promising candidate I selected photoconductive switches and ultrafast ...
