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.

Semiconductor Temperature Monitoring With Series Connected Linear Temperature Sensing Resistors for Averaging Out Manufacturing Variations in the Resistors

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. The temperature signal from a resistor can be analyze a component that corresponds to temperature and an error component that varies in a simple statistical way. In the averag temperature signal produced by the series connection, the error components are also averaged, and the temperature signal is substantially free from this error.
