# What is the truth table for AND gate?

## What is the truth table for AND gate?

The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.

How many transistors are in A AND gate?

Depends on the logic to be implemented. A NOT gate/Intervter has 2 transistors(pmos and nmos). A two input AND gate has a minimum of 6 transistors.

### Is an AND gate just a transistor?

A transistor is an electronic device that has three ends: a source, a sink, and a gate.

HOW CAN AND and OR gate be implemented using transistor?

By using RTL (resistor transistor logic) we have designed the AND gate by two transistors and some resistor. The transistors are connected in series and their bases are used as input. The base of both the transistors act like inputs and one of the emitter of either of the transistors is used to derive the output.

#### How many transistors are there in a 3 input gate?

CMOS NAND or NOR gates require two transistors (one NMOS and one PMOS) per input.

What is the relationship between transistors and gates?

Logic gates are implemented using transistors. So,in a way we can say logic gates are transistors. Transistors can be used as switches and based on the connection they can be used to implement various logic gates. Logic gates are implemented using transistors.

## How many NMOS transistors are used to build an AND gate?

Here’s the general answer for any number of inputs of any NAND, NOR, AND, or OR gate. CMOS NAND or NOR gates require two transistors (one NMOS and one PMOS) per input. AND and OR gates are built from NAND and NOR gates by adding an inverter stage afterwards, which takes one NMOS and one PMOS transistor.

How do you make a transistor NOT gate?

The #base terminal of the transistor is connected to the input A with a 10KΩ (R2) resistor in between them and the emitter terminal of the transistor is connected to the GND. For a NOT Gate, the output Ā is taken at the #collector terminal of the transistor and is then connected to an #LED to observe the output.

### How do you make an AND gate circuit?

To build a logic AND gate you are going to need the following parts:

2. 1x LED (Any color, red was used in this project)
3. 1x 1K Ohm resistor.
4. 2x 10K Ohm resistors.
5. 2x NPN Transistors (I used the 2N2222)
6. 2x N.O. Push buttons (Normally Open)
7. 5x Wires/Jumper Wires.

Is a logic gate a transistor?

“A logic gate in a microchip is made up of a specific arrangement of transistors. For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon.

#### What is a 3-input and gate truth table?

3 Input AND Gate Truth Table As the inputs are multiplied with each other to generate the output, the output of a three-input AND gate is logic high when three of the inputs are at logic high i,e ‘1’. If any one or two of the inputs is “LOW” or at logic zero then the output is also logic zero irrespective of the other inputs.

When is the output of a three-input AND gate logic high?

As the inputs are multiplied with each other to generate the output, the output of a three-input AND gate is logic high when three of the inputs are at logic high i,e ‘1’. If any one or two of the inputs is “LOW” or at logic zero then the output is also logic zero irrespective of the other inputs.

## What is a truth table in circuits?

Tables like this one (providing us with the value of a function for all possible combination of inputs of that function) are called truth tables. Figure 6: Truth table summarizing operation of the inverter circuit (the NOT function). The figure below shows how one could build another circuit using transistors.

What is the truth table of an XOR gate?

The truth table of an XOR gate is; Exclusive-NOR Gate (XNOR Gate) In XNOR gate the output is in state 1 when its both inputs are the same that is, both 0 or both 1. The Boolean expression of XNOR gate
