“…The conversion is done using simple two bits in terms of representation i.e., '1's and '0's. In these binary bits '1' means high or ON and '0' means low or OFF, these are the terms used in computer world or any manufacturing technologies [11][12][13][14][15][16][17]. The Binary code is a weighted code, as it has positional weights whereas, Gray code is a nonweighted code, it does not have any positional weight.…”

Quantum Dot Cellular Automata (QCA) is a prominent technology in Quantum Electronics. This is implemented with the help of quantum cells which are also known as basic building blocks of Quantum Electronics. In QCA technology there are four different clock pulses, clock delay for each clock cycle is 0.25 ns. Using this technology now we are implementing the Binary to Gray code converter. In this paper, we are proposing a design to reduce the number of cells when compared to the previous designs and we are also extending the implementation of the converter up to 5-bits. The number of cells in the proposed design is improved by 2.5%, 36.44%, and 50.66% for 2-bit, 3-bit, and 4-bit respectively. Also, for 3-bit and 4-bit, the total occupied area is improved by 55.56% and 74.680% respectively. In our proposed design it helps us to decrease the area from the previous circuit, which may also lead to the decrease in the power consumption.

“…In the year 2004, Yongli Huang et al have carried out a comparative study of the performance of CMUT for three different membrane configurations [ 12 ]. A compact analytical model was proposed by R. Maity et al to calculate the dependency of collapse voltage on different physical parameters and structural features of the device [ 13 , 14 ]. In another study, the authors have used Mason’s equation to establish a circular membrane model [ 15 ].…”

In the present paper, we have analytically explored the small variations of the local pressure in the trapped air film of both sides of the clamped circular capacitive micromachined ultrasonic transducer (CMUT), which consists of a thin movable membrane of silicon nitride (Si3N4). This time-independent pressure profile has been investigated thoroughly by solving the associated linear Reynold’s equation in the framework of three analytical models, viz. membrane model, plate model, and non-local plate model. The solution involves Bessel functions of the first kind. The Landau–Lifschitz fringing technique has been assimilated to engrave the edge effects in estimation of the capacitance of CMUT, which should be considered in the micrometer or lesser dimension. To divulge the dimension-based efficacy of the considered analytical models, various statistical methods have been employed. Our use of contour plots of absolute quadratic deviation revealed a very satisfactory solution in this direction. Though the analytical expression of the pressure profile is very cumbersome in various models, the analysis of these outputs exhibits that the pressure profile follows the displacement profile in all the cases indicating no viscous damping. A finite element model (FEM) has been used to validate the systematic analyses of displacement profiles for several radii and thicknesses of the CMUT’s diaphragm. The FEM result is further corroborated by published experimental results bearing excellent outcome.
