    delay calculation Reply

    i want to calculate delay for my circuit.my circuit is designed based on GDI-technique.

    In the normal cmos circuit, vinput is nothing but a pulse.

    If i give pulse ,i knew how to calculate delay.but in my circuit gate voltage(vinput) is dc.

    in Dc there is no rise and fall delay,then how can i calculte the delay

    With regards

    I must admit I'm not really familiar with the GDI technique (I did a quick google search to enlighten myself a little). There are a number of papers which talk about simulation - for example http://arxiv.org/abs/1207.2840 . I didn't spend too much time on this, but I can only imagine that for this to be a useful technique, you must be able to have signals that change and are not stuck at DC. Measuring delay with DC signals sounds like an oxymoron to me, and I don't see why you can't varying the inputs and then see how the outputs change in order to measure delay.

    I suggest you do some more research as to how others have tackled this by consulting papers written on this topic.

    Regards,

    Andrew.
