Dear all,
If I have a long metal wire,I will consider delay time question.
Maybe I will add inverter to improve delay time.
Besides this method, does everyone have anothor method?
Thanks.
My goal is my metal line is control that transmission gate.
But it may be too longer.Adding extra circuitry will only increase the delay.
I have another question. Can inverter chain not a method?
How do I add an equal delay to the other paths?
Thanks.
A universal method of removing skew from clocks is the use of a Delay-Locked Loop, but in your case, it will be overkill.
If it is just a wire we are talking about, you can minimize the delay by
1) careful placement of the blocks generating the signals.
2) Using an extra buffer
3) Using a transmission gate(s)(always enabled) to add more delays to the other signal.
4) Using a differential cell on the 'main' signal and generating two local signals that are 180 deg apart and using these to control the transmission gate.
