ABSTRACT:
A circuit and method for compensating for variations in voltages in a circuit or device that are caused by temperature changes imposed on the circuit or device. The circuit is a temperature-controlled attenuator that comprises an input and an output. The input is to be coupled to a point in the circuit or device carrying the temperature-dependent voltage. At least one thermistor is coupled between the input and the output by a resistor network. The resistor network comprises a plurality or resistors whose values are selected based upon selected points on the temperature-voltage curve for the circuit and a desired compensated voltage.
