Hello,

Currently I am designing a tx current mode driver .Output has the expected values but there is a problem,I see some glitches at the output that are not desirable. Is there any possible way to fix and smooth my output during time?

Thanks in advance! :smile:
 

Look to your final stage current control scheme. A hard-banging
switched gate will inject Miller spikes on every transition. A
source-current-steering scheme can inject much less. Now if
the glitches appear when the output should be settled, that
is another sort of mystery.
