Abstract
The present invention describes a resistance reference circuit that includes a reference resistor that is substantially independent of temperature variations to which the resistance reference circuit is subjected. Also provided is a resistor network that may be dependant upon the temperature variations, and a current source circuit that provides first and second currents to the reference resistor and the resistor network. A circuit that is responsive to voltages developed across the reference resistor and the resistor network modifies the resistance value of the resistor network such that its resistance value is maintained the same as that of the reference resistor.
