# How many transistors are needed for an AND gate?

## How many transistors are needed for an AND gate?

AND, OR gates: 3 transistors. NAND, NOR gates: 2 transistors.

### WHAT IS AND OR invert gate?

AND-OR-Invert (AOI) logic and AOI gates are two-level compound (or complex) logic functions constructed from the combination of one or more AND gates followed by a NOR gate. The complement of AOI Logic is OR-AND-Invert (OAI) logic where the OR gates precede a NAND gate.

#### What does an AND gate do in a circuit?

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.

What is the difference between OR AND AND gate?

Both AND logic gate and OR logic gate are the two basic logic gates used in digital circuits. The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.

How many transistors are in a 2 input AND gate?

A 2-input NAND gate requires 4 transistors.

## What is a gate in a transistor?

“In a computer, a gate controls the flow of electric current through a circuit. The gate consists of transistors; the transistors are selected by the chip designer from two basic types (PMOS and NMOS transistors) that are found in the ubiquitous CMOS (complementary metal-oxide semiconductor) technology.

### What is inverted OR gate called?

Inverted AND gate is called NAND gate and Inverted OR gate is called NOR gate.

#### Which gate is equal to or invert gate?

NAND gate
A NAND gate is equivalent to an inverted-input OR gate. An AND gate is equivalent to an inverted-input NOR gate. A NOR gate is equivalent to an inverted-input AND gate. An OR gate is equivalent to an inverted-input NAND gate.

What is the difference between OR gate and NOR gate?

The NOR gate is a combination OR gate followed by an inverter. Its output is “true” if both inputs are “false.” Otherwise, the output is “false.” The XNOR (exclusive-NOR) gate is a combination XOR gate followed by an inverter. Its output is “true” if the inputs are the same, and “false” if the inputs are different.

What is the truth table of OR gate?

Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate. OR Gate: An OR Gate is an electronic circuit that gives a true output (1) if one or more of its input are true. (+) is used to show the OR operation.

## What is the function of OR gate?

The function of an OR gate is to find the maximum between the inputs which are binary in nature. It is one of the basic gates used in Boolean algebra and electronic circuits like transistor-transistor logic, and complementary metal-oxide semiconductors make use of it.

### What are the 2 differences between an AND gate AND an OR gate?

What is the difference between AND gate and OR gate? 1. AND gate gives a ‘true’ output only when both inputs are ‘true’, whereas OR gate gives an output of ‘true’ if at least one of the inputs is ‘true’. AND gate implements logical conjunction and OR gate implements logical disjunction.

#### How does or gate using transistor work?

Transistor OR Gate. The use of transistors for the construction of logic gates depends upon their utility as fast switches. When the base-emitter diode is turned on enough to be driven into saturation, the collector voltage with respect to the emitter may be near zero and can be used to construct gates for the TTL logic family. For the OR logic, the transistors are in parallel and the output is driven high if either of the transistors is conducting.

What are logic gates and transistors?

Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements.

What are the uses of logic gates?

Logic gates can also be used to store data. A storage element can be constructed by connecting several gates in a “latch” circuit. More complicated designs that use clock signals and that change only on a rising or falling edge of the clock are called edge-triggered “flip-flops”.

## What is a logic gate circuit?

Logic Gating gene circuits are designed to integrate information about multiple targets with biological logic in order to enable the more accurate and efficient targeting of heterogeneous disease cells while sparing healthy ones.
