Abstract

A number of temperature sensitive resistors are each located on or near one of a number of semiconductor devices. The resistors are connected in series with the input terminals of a conventional circuit that converts the resistance of the circuit to temperature signifying signal. The temperature signifying signal is used conventionally to control a cooling mechanism for the circuit or to activate an alarm. The circuit uses temperature sensitive resistors that have a a linear temperature-resistance function, and the resistance of the circuit is a function of the sum of the temperatures of each resistor. Thus, the temperature signal is proportional to the average temperature of the resistors.
