摘要： Enhanced linearity, low switching perturbation resistor string matrices. The resistor strings are arranged in an array of a plurality of rows of resistive elements and electrically arranged with rows equally spaced above and below the physical centerline of the array being coupled together in an opposite sense. Preferably also physically adjacent rows are equally spaced from the center of the electrical order of rows. This connection prevents accumulation of errors due to vertical and horizontal resistance gradients over the array. Also node selection by controlling node select transistors coupled to column select lines to select one node in each row, and also controlling row select transistors to select the row of the desired node minimizes settling time after a tap change by inducing equal and opposite voltage changes at points close together along the resistor string, whether in the array of the present invention or in the snake configuration.

摘要： A plurality of protective resistors can be easily inserted between circuit forming elements, and opposite ends of each protective resistor can be properly press-contacted to each circuit forming element. The protective resistor can be easily replaced when broken. A resistor array board comprises a porous plate having a plurality of through-holes arranged in array and opening at opposite surfaces thereof; and a plurality of protective resistors removably loosely inserted into the through-holes, respectively. Each of the protective resistors are resiliently retained by an electrically conductive spring element, and opposite ends of each of the protective resistors are press-contacted with the circuit forming elements which are arranged in opposing relation on surfaces of the porous plates.

摘要： A ball grid array resistor network has a substrate that has top and bottom surfaces. Resistors are disposed on the top surface. Conductors are disposed on the top surface, and each conductor is electrically connected to an end of each resistor. Vias extend through the substrate and are electrically connected to the conductors. Solder spheres are disposed on the bottom surface, and are electrically connected to the vias. A cover coat is disposed over the conductors and resistors. In an alternative embodiment, the vias are eliminated and the resistor network is formed on the bottom surface of the substrate. The resistor network provides a high density of resistors per unit area.
