Question

Consider the function Y=AB+C(D+E)​

a. Draw the CMOS schematic for the function. Label all sources and drains.

Answer 1

Creating a detailed CMOS schematic for the function
`\(Y = AB + C(D + E)\)` involves using NMOS and PMOS transistors with NAND and NOR gates.

Step-by-step explanation:

Creating a detailed CMOS schematic involves multiple components such as NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) transistors. I'll provide a simplified example using basic logic gates to represent the given function
`\(Y = AB + C(D + E)\)`.

Assuming that A, B, C, D, and E are the inputs, and Y is the output, let's represent the logic gates for each term in the function:

1. NMOS and PMOS Transistors:

Use NMOS transistors for the n-type logic gates and PMOS transistors for the p-type logic gates.

2. Basic Logic Gates:

Use NAND and NOR gates to represent the logic operations.

3. Labeling:

Label the transistors and their connections, indicating the sources and drains.

Here is a simplified representation of the CMOS schematic:

```

A B C D E

| | | | |

-----o-------o-------o-------o-------o-----

| | | | |

=== === === === ===

| | | | |

| | | | |

NAND NAND NOR NOR (Output Y)

| | | | |

-----o-------o-------o-------o-------o-----

| | | | |

```

In this schematic:

The inputs A, B, C, D, and E are connected to the gates of NMOS and PMOS transistors.

NAND gates are used for the terms AB and C(D + E).

NOR gate is used to combine the results of the NAND gates.

The final output Y is taken from the NOR gate.

This is a simplified representation, and the actual design may involve more complex arrangements of transistors and gates depending on the technology used and specific design constraints. If you need a more detailed schematic, it's recommended to use a dedicated Electronic Design Automation (EDA) tool for CMOS circuit design.
