  • Monolithic temperature compensation scheme for field effect transistor integrated circuits
    Patent number: 6548840
    Abstract: A method and apparatus for substantially canceling the effects of temperature on the electrical performance of Field Effect Transistor (FET) integrated circuits (IC's) by exploiting a subtle feature of an epitaxial resistor implemented in an FET process. Specifically, the invention takes advantage of two constituent epitaxial resistor components having resistances that vary monotonically in opposite directions as functions of temperature. The invention includes a method for selecting the geometry of such an epitaxial resistor to give it either temperature invariance or a specific, useful functional temperature dependence.
