Question
**Title:** Designing a 4-Bit Adder Using CMOS **Problem Statement:** A circuit designer developed the layout below to design a 4-bit adder. **Tasks:** A) Provide the Boolean function of the layout. B) Draw a CMOS schematic using Electric and take a snapshot of it. **Layout Description:** - **Visual Components:** - The layout includes regions labeled as PMOS and NMOS transistors, which are fundamental components of CMOS technology. - The topmost horizontal line is marked as VDD (power supply), and the bottom is GND (ground). - Inputs are labeled as C0, P0, and G0, located on the left side of the layout. - There is an output label, F, represented at the right side. - **Color Coding and Connectivity:** - **Red and Blue Lines:** Indicate the connections between the transistors, possibly representing metal or polysilicon lines for connectivity. - **Green Rectangles:** Mark the locations of the PMOS and NMOS transistors, separating different stages of computation. - The pink-colored paths intersecting the transistors show possible polysilicon gate connections. This layout is a visual representation used to generate a 4-bit adder circuit on a CMOS platform. The task requires interpreting this layout to form a Boolean function and use design software like Electric to create a CMOS schematic representation.
