Parasitic delay of inverter
Web8 Mar 2024 · The fine delay comprises eight codes per coarse code and has about 50 ps steps that cover more than one coarse delay step. The simulated results for three delays ( t d , 2 t d , 3 t d ) are t d , 1.92 t d and 2.61 t d respectively, which are not exact integer multiples because of the incomplete voltage settling across pull-up and pull-down … Web28 Apr 2014 · As an experiment we increase W of nMOS and pMOS and each time we increase W, we find the delay of the inverter (using spice). We notice that while increasing …
