Abstract-This paper investigates the constructing of basic logic gates (AND, OR, NAND, NOR, and XOR) by using CMOS logic and ALTERNATE GATE CIRCUITS namely, Pseudonmos, Passtransistor, Multiplexer, Transmission Gate to perform logic operations without changing the circuit topology. CMOS suffers from increased area and correspondingly increased the capacitance and delay as the logic becomes more complex so for this reason Alternate Gate circuits are developed and these type of circuits can be used as supplement to the complementary type circuits. These forms are not intended to replace CMOS but rather to be used in special applications for special purposes. The advantages and limitations of CMOS family over BJT, Pseudonmos, Pass transistor, Transmission are discussed in this paper.

“…This T gate works as a NAND gate at a fixed control polarization C= 0.40 and works as NOR gate at C= -0.40. Hence to implement the NAND gate the fixed polarization C is kept to 0.40 polarization [1], which provides a particular orientation to the electrons to be settled after tunneling through the tunneling barrier. This T gate operates by the concept of partial polarization effect.…”

Molecular quantum-dot cellular automata (QCA) is an emerging nanocomputing paradigm, which operates on electrostatic repulsion phenomena between two electrons to keep those apart at the maximum distance to a rest position for obtaining the highest finding probability. In the field of Quantum-dot Cellular Automata the digital logic gate approaches nearly about to nanometer in scale. In QCA quantum gates operate by the tunneling effect of electrons from one quantum dot to another dot through revealing its wave nature. The operating speed of the device gains the speed of light because the quantum tunneling occurs at the light speed. This paper compares two methodologies of quantum logic gate designing, those are universal T gate designing and conventional gate designing practice. One 22 cells 2x1 MUX is proposed which is designed by conventional method, that provides 20.35% optimization in area occupancy compared to the best reported designs. Furthermore, one 11 cells 2:1 MUX layout is proposed which achieves 33.33% area reduction compared to the best ever multiplexer designed in QCA technology.

Quantum-dot cellular automata is a molecular logic synthesis technology which is the utmost instance for the shift of microelectronics technology towards the molecular electronics. Nowadays the quantum-dot cellular automata has been playing a major role in the list of the most emerging quantum information computation techniques. Quantum-dot cellular automata is a nanoscale information computational technology which operates through the quantum bits that are temporarily created as a result of electron tunneling in between two qdots. This is an electron configuration based device which utilizes the electrostatic repulsive force to initialize a particular binary logic state based on electronic orientation inside quantum dots. In this paper a few novel methodologies for binary logic gate designing have proposed which are highly optimized in terms of area occupancy and clock latency. Using the proposed universal gates one adjoined half adder-half subtractor, 1 bit comparator and 2 to 1 multiplexer layouts have designed. Moreover, the temperature stability factor for the proposed circuits have also analyzed to reveal the dynamic errors of the circuits during its operation. This temperature stability factor asserts that both of the proposed circuits' adjoined adder-subtractor and the 1 bit comparator have the same operating range of temperature within 1 K to 6 K. Moreover, the cell wise power dissipation analysis for proposed gates has also performed to specify the input polarization strength limit.
