Hi,
I am using an LM 311 comparator chip for comparing a dc signal(+input) with a 200 KHz triangle wave(- input)-p-p 6 V, starting from 0.
The output has a pullup resistor of 470 ohm connected to +5V and is one of the logic inputs of a CMOS AND gate CD4081BE.
There is no feedback provided in the comparator.
But still I get a delay of about 200ns..i.e after the triangle wave goes above the dc signal it takes about 200 ns for the output of the comparator to fall to 0 from +5.
Why is this hapenning?
Can anybody suggest something so that I can somehow get rid of this delay?
