Layout of R_2R DAC

This lab taught how to create layouts and subcells in eletric VLSI

This lab requires the eletric VLSI software

Task 1: Create the schematic of the subcells for the R-2R ladder. (40 points).

Task 2: Create the layout of the subcells for the R-2R ladder. (50 points).

Conclusion: The use of subcells allows for more neat and efficent design. The layout sucsefully simuelated the DAC with the same results as the schematic
