Comparator Equal INPUTs

[find_beat]

I have a problem with the comparator when there are equal inputs to the pA

- > + : output is negative
+ > - : output is floating

I want it to that - = + : output is also negative

How can I do this?

hi,
Please post a circuit.

Are you asking about digital or analog comparators.?

Hi,

Just curious, would a little hysteresis help your project?

If you want two equal comparator inputs to give a negative output then you could bias the non-inverting input negatively or the inverting input positively.

Thank you guys. I got the solution by using a PNP transistor.

Problem I'm having now is EAGLE CAD... how can make round edges of the board?
