Here we have a 10K resister given by the length and width in relation to Rsquare

Lab 3


We will layout a 10K resistence, for the C5 Process the Resistence is about 855 ohms, and if we use the width 4.5 for the resister we can calcualte length by solving the following equation.

res with dem



We can DRC it at this stage to see we have 0 errors

drc for res

Make sure to make the length and width divisible by 0.15 to prevent DRC errors.

 math

We get roughly 56um, we want to make sure the values are divisible by 0.015um

Using this resister we can create a new layout in our previous schematic.

Here we can see the start with D9:

We can see ground here:

Now Lets LVS to see if the layout and schematic match.
