hi

i need some help.
i made a zero cross detector circuit and connect it to a differential circuit .
the problem is the current isn't completely zero when it suppose to(0.1V or so) and cause the circuit to differentiate that part too .

any idea how to solve this problem

thanks

I don't see your circuit but anyway try applying a slightly negative bias voltage to remove any leakage currents.

Please clarify. You say a current isnt completely zero but then you say that it is 0.1 Volts or so. Well, is it volts or current that you are talking about?

Is it the output or something on the input that doesnt go to zero?

hi
actually i am talking about both volts and current . after all V=IR
anyway it is during the output that the voltage doesn't go down to completely Zero when it supposed to

any help is appreciated
thanks

You need to post the circuit, what you're describing doesn't make a great deal of sense. Also some idea of what you are trying to do would be helpful.
