ABSTRACT:
A circuit for sensing on-die temperature at multiple locations using a minimum number of pins is described. Thermal diodes coupled to pins are placed on a die to measure the temperature at various die locations. Voltage is applied to the pins to determine the temperature at each given diode location. The polarity of the voltage applied across the pins determines what diodes are selected for measurement.
