## What is not logic gate? A gate equivalent (GE) stands for a unit of measure which allows specifying manufacturing-technology-independent complexity of digital electronic circuits. ... Basically, a two-input drive-strength-one NAND gate in CMOS technology consists of four transistors.

A gate equivalent (GE) stands for a unit of measure which allows to specify manufacturing-technology-independent complexity of digital electronic circuits.For today's CMOS technologies, the silicon area of a two-input drive-strength-one NAND gate usually constitutes the technology-dependent unit area commonly referred to as gate equivalent.A specification in gate equivalents for a certain circuit reflects a complexity measure, from which a corresponding silicon area can be deduced for a ...

## Can and gate have 3 inputs?

Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.

## What gate is equivalent to OR gate?

An OR gate can be replaced by NAND gates as shown in the figure (The OR gate is replaced by a NAND gate with all its inputs complemented by NAND gate inverters). Thus, the NAND gate is a universal gate since it can implement the AND, OR and NOT functions.

## Why are universal Gates called that?

NAND and NOR gates are known as universal gates. They are called universal gates because they can perform all logic functions of OR, AND, and NOT gates.

## Which gate is an inverted AND gate?

Inverted AND gate is called NAND gate and Inverted OR gate is called NOR gate. इनवर्टर गेट किस गेट को कहा जाता है।  ### Which gate is equivalent to bubbled gate?

The NOT gates are to be added to the inputs of AND gate, it will give the NOR gate output. Because, bubbled AND gate will acts as a NOR gate. Therefore, bubbled NAND gate is equivalent to OR gate.

### What is gate unit?

A gate equivalent (GE) stands for a unit of measure which allows specifying manufacturing-technology-independent complexity of digital electronic circuits. ... Basically, a two-input drive-strength-one NAND gate in CMOS technology consists of four transistors.

### Which gate is equivalent to NOR OR XOR?

The XNOR gate (also known as a XORN'T, ENOR, EXNOR or NXOR) – and pronounced as Exclusive NOR – is a digital logic gate whose function is the logical complement of the exclusive OR gate (XOR gate). Logically, an XNOR gate is a NOT gate followed by an XOR gate.Oct 11, 2020

### What is bubbled and gate?

Bubbled AND gate: The AND gate with inverted inputs is called as Bubbled AND gate which is also called as negative AND gate. NOR gate is also called as an active low AND gate since its output becomes high only when all its inputs are equal to 0.Mar 5, 2020

### Is XOR a universal gate?

You can't derive an OR (or AND, NOR, NAND) gate from only XOR (or XNOR) gates, because they are not universal gates. Here is an argument against XOR and XNOR as universal gates. An XOR gate is a parity generator.Jun 20, 2015

### What is the only function of NOT gate?

Hint: A NOT gate is one of the logic gates (or one can say a Boolean Operator) which can take only one input signal and gives one output signal. The NOT gate works by inverting the original signal.

### Which gate has only one input?

NOT gate (inverter)

A NOT gate can only have one input and the output is the inverse of the input. A NOT gate is also called an inverter.

### What is a gate equivalent (GE)?

• A gate equivalent (GE) stands for a unit of measure which allows specifying manufacturing-technology-independent complexity of digital electronic circuits. For today's CMOS technologies, the silicon area of a two-input drive-strength-one NAND gate usually constitutes the technology-dependent unit area commonly referred to as gate equivalent.

### What is the difference between and gate and or gate?

• An AND gate is simply the inverse of a NAND gate and so following a NAND gate with a NOT gate (made from a NAND gate) gives the logic equivalent of an AND gate. The first logic gate is the NAND gate. The second logic gate is a NOT gate which inverts the output of the NAND gate to give the output required for an AND gate. The OR gate

### Which logic gate is equivalent to a bubbled and gate?

• In digital integrated circuits (ICs) we will find an array of the logic gate area unit. First theorem – It states that the NAND gate is equivalent to a bubbled OR gate. Second theorem – It states that the NOR gate is equivalent to a bubbled AND gate.

### What is the logic equivalent of a NOR gate?

• A NOR gate is simply the inverse of an OR gate and so following a NOR gate (made from NAND gates) with a NOT gate (made from a NAND gate) gives the logic equivalent of a NOR gate. The first three logic gates make the OR gate. The final logic gate acts as an inverter and makes the OR gate into a NOR gate.

### What is the logic equivalent of an AND gate?What is the logic equivalent of an AND gate?

The AND gate An AND gate is simply the inverse of a NAND gate and so following a NAND gate with a NOT gate (made from a NAND gate) gives the logic equivalent of an AND gate. The first logic gate is the NAND gate. The second logic gate is an NOT gate which inverts the output of the NAND gate to give the output required for an AND gate.

### What is the difference between and gate and or gate?What is the difference between and gate and or gate?

An AND gate is simply the inverse of a NAND gate and so following a NAND gate with a NOT gate (made from a NAND gate) gives the logic equivalent of an AND gate. The first logic gate is the NAND gate. The second logic gate is a NOT gate which inverts the output of the NAND gate to give the output required for an AND gate. The OR gate

### What is gate equivalent in cell library?What is gate equivalent in cell library?

Gate equivalent. The standard cell library comprises many different logic gates, for example a NAND gate. For each logical type of logic gate, e.g., a two-input NAND, there usually exist different physical realizations in the standard cell library, for instance with different output drive strengths.

### What is gate equivalent in CMOS?What is gate equivalent in CMOS?

Gate equivalent. Basically, a two-input drive-strength-one NAND gate in CMOS technology consists of four transistors. If higher output drive strength is required, an additional output driver stage of four transistors is added.
