CMOS CIRCUIT FOR XOR GATE
XOR gate - Wikipedia
XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true both inputs are false (0/LOW) or both are true, a false output results.
Exclusive OR Gate(XOR-Gate) - Electronics Hub
Jul 14, 2015XOR Gate equivalent circuit. The EX-OR gate is defined as, the hybrid logic gate with 2 or more inputs to perform the exclusive Disjunction operation. The XOR circuit with 2 inputs is designed by using AND, OR and NOT gates is shown above. The output of 2 input XOR gate is HIGH only when one of its inputs are high.
Logic gate - Wikipedia
A logic gate is an idealized model of computation or physical electronic device implementing a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal logic gate, one that has for instance zero rise time and unlimited fan-out, or it may refer to a non-ideal physical device (see
What is logic gate (AND, OR, XOR, NOT, NAND, NOR and XNOR
The AND gate is so named because, if 0 is called "false" and 1 is called "true," the gate acts in the same way as the logical "and" operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate. (In the symbol, the input terminals

2 : 1 MUX using transmission gate. 2 : 1 MUX using transmission gate : A 2:1 multiplexer is shown in Figure below. This gate selects either input A or B on the basis of the value of the control signal 'C' control signal C is logic low the output is equal to the input A and when control signal C is logic high the output is equal to the input B.
OR Gate: What is it? (Working Principle & Circuit Diagram
Sep 27, 2020A simple two inputs OR gate can be realized by using a diode as follows, In the above circuit, if A and B are applied with 0V, there will be no voltage appears at X. When any of the inputs is given with +5V, the respective diode becomes forward biased and behaves as ideally short circuited hence this +5 V will appear at output X. +5 V means logical 1.[PDF]

Designing a XOR gate looking at figure 12 shows that the topology of this circuit consists of two extra inverters and we have a total of 12 MOSFETs in this design of a XOR gate. Keep the NMOS size the same, but change the PMOS to 20/10. Here is my schematic deisng, icon, and layout of an XOR gate:
Gate level modeling in Verilog - Technobyte
Mar 01, 2020Designing circuits using basic logic gates is known as gate-level modeling. A digital circuit is implemented using logic gates and interconnections between these gates. The primitives (The most basic commands of a language) defined in Verilog have been set keeping the user requirements in mind making it easy to design bigger blocks.
