Disclosed are systems, methods, and algorithms for network layout. A network layout having subnetworks of matching series and parallel elements is systematically generated to implement the network within area constraints. After the selection of the number of rows of network elements, the number of elements in each row, the sequencing of the elements, and the element locations, are systematically determined. The network layout systematically produced reduces the influence of unfavorable factors on the network such as temperature gradients, process gradients, and interference, by dispersing subnetwork elements throughout the layout.

Layout of network using parallel and series elements

Layout of networks using parallel and series elements

The invention provides an algorithm for systematically determining and optimizing the physical implementation of an array of networks with a combination of matching series and parallel elements. Disclosed are the machine-implemented steps of defining the network in terms of a network value representing the sum of the elements. The network value is divided into an integer part and a proper fraction part. A partial quotient and residue are computed for the proper fraction part. Additional partial quotients and residues may be computed while the residue is significant. The physical implementation of the network is then described in terms of series and parallel elements represented by the integer part and the partial quotients. Also disclosed is a method of assembling a network from a combination of series and parallel elements. A network value consisting of an integer part and a proper fraction part are used to represent the network. A partial quotient and residue are computed for the proper fraction part, using as many iterations as needed until the residue becomes insignificant. The physical implementation of the network is described in terms of series and parallel elements represented by the integer part and the partial quotients and the described elements are coupled to form the network. A system for constructing a network from a combination of matching series and parallel elements is also disclosed. Means for executing an algorithm to determine the physical implementation of the network and means for coupling a quantity of matching series and parallel elements to form the network are indicated.
