  • Patent number: 4079337
    Abstract: A wide bandwidth characteristic is provided for use as in a negative feedback amplifier by a deposited resistor arrangement. The arrangement includes a basic feedback resistor having a high resistance value and a narrow elongated shape. Closely positioned on the same substrate and physically parallel are one or more low value resistors having the same length and with adjacent points on the respective resistors being at the same electrical potential. The feedback capacitance is greatly reduced by the extra length. The capacity to ground, and thus the displacement current, is essentially eliminated since most of the stray capacitance is between points of equal potential.
