Layout the R-2R DAC

Introduction
- The purpose of this lab is to continue working with Electric VLSI and view different approaches to creating schematics.

Materials and Methods
- Electric VLSI

Results
Task 1: Create the schematic of the subcells for the R-2R ladder. (40 points).
For the first task, we are to re-create the R-2R ladder from the previous lab but using subcells.

Here is my schematic and icon:

Figure 1: R-2R ladder schematic created using subcells.

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

First, we created the layout of the R-2R subcells:

Figure 2: Layout of the subcell.

Then built the schematic for the R-2R v2:

Figure 3: Schematic of the R-2R Ladder v2.

Here are the results from the simulation:

Discussion
This lab was a great way to practice using Electric VLSI.
