Introduction:
In this lab we were introduced to subcells and how they can be used when designing major projects.

Task 1: Create the schematic of the subcells for the R 2R ladder

Figure 1: DRC clear for schm of N-RWELL resistors for subcell


Figure 2: DRC clean for N-RWELL with icon


Figure 3: N-RWell layout for subcell, also shows DRC clean

Task 2: Create the layout of the subcells for the R- 2R ladder


Figure 4: Schematic view of R 2R ladder using subcells


Figure 5: Layout view of R 2R ladder using subcells


Figure 6: NCC clear for R 2R ladder


Figure 7: LTSpice simulation of new R 2R ladder in ADC R 2R DAC simulation

Conclusion:
Overall this was a good lab to understand the usefullness of using subcells and I beleive that they will continue to be useful throughout the semester.
