Hello to all.
First post on this forum, I 'd like to say I am pretty happy I found a place it seems I can got some help (and exchange ideas!).
I have this project where I am testing the behavior of comparators when they are fed with two (continously changing) inputs into is terminals,
instead of having a signal in one input and a "voltage reference" to the other.
See schematic below.
The main reason for this post is that it seems I have encountered a problem which I found suprising:
Since the signals fed into the comparators' inputs are starting at the same point, during low voltage/fast signals the comparator is not being able to cope with that and does not trigger (start) a pulse from the point it should; but from a point a little later.
Can anyone please advise me on the nature/causes of the problem?
I have been asking some firends and they said that this could be solved by a delay line into the "red" input" (?)
Yet, I am a little concerned about the fact that a delay line could cause a considerable amount of addition of noise.
So, is there someone of you who who can think of a "noiseless" delay circuit?
or perhaps another solution to my problem?
Regards,
Futurama.
