Reflection example of ads2020 simulation signal

        Through the study of front face high-speed signal reflection , We have theoretically understood the reflection of the signal , Let's take a look at the reflection of the signal with the help of the high-speed signal simulation tool . The following figure is a typical model bounce diagram simulation circuit .

R1 Is the internal resistance of the signal source ,TLIN Is an ideal transmission line model ,V1 Test points for the near end ,V2 For remote test points .

        The waveforms of time and measuring points obtained by simulation are as follows ： after 1ns, The signal reaches the source , The amplitude of the far end is

                                                1.66v=1 * ( 50 / 60) * 2

It can be seen from the simulated waveform that the amplitude is also approximately 1.66v, This also verifies our theoretical analysis .
