ABSTRACT:
A resistive network formed on a substrate includes film resistors formed of resistive elements, each element having a plurality of portions symmetrically disposed relative to two axes of symmetry. The biaxially symmetric arrangement provides uniform resistance characteristics for the various film resistors, thus improving stability of resistance ratios among resistors of the network. TCR tracking for the film resistors, i.e., the TCR of a ratio of the resistors, is similarly improved. Where the elements of different resistors of the network are interleaved, the temperature of the different resistors is also made more uniform.
