Download scientific diagram | NOT gate designs in QCA from publication: Design of a CDMA Transmission Reception Unit in Quantum Dot Cellular Automata | Quantum Dots are nano …

Majority gate and inverter (NOT) gate are considered as the two most fundamental building blocks of QCA. Figure 5 shows a majority gate with three inputs and one output.

The frequently used QCA NOT gate (Fig. 4) is based on the fact that the input signal comes from the left of a QCA wire and splits into two parallel offset wires. The signal is inverted at...

These features make it an appropriate alternative to the CMOS technique. This paper suggests three novel structures of XNOR gates in the QCA technology.

Some of the essential reversible gates are: NOT gate is a 1*1 gate and an elementary gate. The quantum cost of not gate is zero. Table 1. Truth table of NOT gate. It is a 2*2 reversible gate …

Mar 29, 2023 · This paper proposes a novel reversible logic circuit such as the Toffoli or CCNOT (controlled-controlled-not) gate in QCA for nanotechnology using an XOR logic gate. The …

Based on this study the proposed paper designed three different kinds of encoder circuits using QCA technology. Following paper used layered 2-input NAND gate and NOR gates to design …

Jun 1, 2022 · NOT gate design in QCA is placing the cells in 450, which inverts the input signal. Output is in the cell which is at clock 0 as shown in Figs. 6 and 18: NOT GATE Waveform. (5) …

Jun 1, 2022 · Each QCA circuit design has a “Driver cell” at the Input port, which drives the wires and gates. These driver cells impose binary logics on the adjacent cells of the wire or gates to …

A technology called Quantum Dot Cellular Automata (QCA) offers a far more effective computational platform than CMOS. Through the polarization of electrons, digital information is...
