Abstract:
A thermal sensor providing simultaneous measurement of two diodes. A first diode and a second diode are coupled to a first current source and a second current source, respectively. The ratio of the currents provided by the two sources is accurately known. The voltage across each of the two diodes may be coupled to the input of a differential amplifier for determination of temperature. Alternatively, the first diode may be coupled to a first current source by a resistor with a known voltage drop, and the second diode may be coupled to an adjustable second current source. The current in the second diode may be adjusted until the voltage across the second diode is equal to the sum of voltage drop across the first diode and the known voltage drop across the resistor. Under the established conditions, the Diode Equation may be used to calculate a temperature.

Claim (Index 1):
A controller for an on-chip thermometer comprising:\n an operational amplifier having a first input coupled to a voltage reference, a second input and an output for coupling to said thermometer; a current source coupled to said output of said operational amplifier and to first and second diodes, wherein said current source comprises an array of current source elements; and a resistor having a first terminal and a second terminal, wherein said first terminal is coupled to said current source and to said second input of said operational amplifier; wherein said controller is operable to cause a first current in said first diode to be fixed while varying a second current in said second diode responsive to a feedback signal to alter the ratio of said first and second currents.
