“…It is necessary to point out that although different types of m × n resistor network models have been studied in literatures, [8,[16][17][18][19] the resistors in those studies, arranged on the horizontal axis, are all regular resistors or special resistors (zero resistance), and the problem of arbitrary network with arbitrary resistors on the upper and lower boundaries has not been solved before. In particular, the Laplacian matrix (LM) approach [8] cannot resolve the complex resistor networks with arbitrary resistors, in other words, Wu's LM method cannot solve the network model structured in Figure 1.…”

Here the problem of equivalent resistance of general 2 × n‐order resistor networks with four different resistor parameters is investigated, and innovations in theory and method are made. Here, the second‐order matrix equation model and boundary condition equation model are established by the RT‐I technique (recursion–transform theory based on current parameters), and the general solution and the special solution of the matrix equation are given by using the matrix transformation method. The current distribution law in the circuit is obtained, and three equivalent resistance formulas of general 2×n‐order resistor networks are obtained. Finally, by analyzing and discussing the special case of the conclusion, the relationship between different resistances is obtained, and the results are compared with those of other literatures.

“…The second technique used is called the recursion transform method; it is based on the solution of a recurrence relation given by a matrix transformation of the equations involving the electrical currents. It was developed by Tan in 2011 21 to compute the equivalent resistance of a finite resistor lattice with diverse architecture such as a square grid, 22,23 complex networks, 24–26 circuits with different boundaries, 27,28 a cobweb networks, 29,30 and cylindrical topologies 31,32 . In spite of the fact that the method is applied to many complex topologies, it is limited to the homogeneous circuit without a localized feeding source.…”

This work deals with a theoretical study of a triangular electrical lattice built on two layers. First, the auxiliary source notion is introduced for characterizing the potential difference over each electrical element, then the mathematical formalism of the Wave Concept Iterative Process (WCIP) method is developed and adapted to the studied circuit. The method is based on the concept of the incident and reflected waves which are defined from the current and voltage at each branch of the circuit. Two relations connecting the waves are established into two definition domains: a spectral domain using the Kirchhoff laws and the auxiliary source connections and another spatial domain defining the boundary conditions and the circuit design. Hence, a system of two equations is obtained, and it is resolved by an iterative process; the transition between the two domains is ensured by the fast Fourier transform and its inverse. Moreover, the equivalent impedance between the feeding source and the nodes of the bottom layer has been calculated.Among the numerical simulation methods, this method has demonstrated its performance for analyzing various designs of the networks including resistors-inductors (RL), resistors-capacitors (RC), and resistors-capacitorsinductors (RLC) circuits excited by a lumped voltage source. The effect of the circuit parameters on the electrical currents and equivalent impedance has been studied.

“…One of the most used components in electrical and electronic circuits is resistors, and several studies have been conducted to compute the value of resistors in various applications, [1][2][3][4][5][6] but the tolerance of resistors is seldom incorporated into the calculations. The tolerance of the resistor is an important parameter of the resistor, which tells us about the amount by which the resistance of the resistor may vary from its specified value during the operation.…”

Resistors come with different tolerances, but they are generally not seriously considered in circuit simulation as only the exact resistances are used. In actual implementation of a resistor network, the tolerance of the resistors used can affect the performances of the network, especially when the network consists of large number of resistors. This work demonstrates the use of the statistical design of experiment methods combined with circuit simulator to obtain the optimum value of the tolerances for different resistors in a resistor network for an application used in proton therapy. The discretized positioning circuit consisting of 86 resistors of four different values (R1 = 1KΩ, R2 = 600 Ω, R3 = 300 Ω, and R4 = 100 Ω) is analyzed for three tolerances of 0.05%, 0.1%, and 0.5%, respectively, and maximum variation in the output signal is observed for 0.5% tolerance. Resistors with values of R1 and R4 are dominant in numbers (56 with R1 and 22 with R4 out of 86 resistors) in the network, and hence, their effect is observed to be significant on the output as expected. Significant interactions between resistors are also observed.
