Patent ID: 6876250

Claim:
A temperature sensor circuit for an integrated circuit chip, said circuit comprising: means for generating a reference parameter, the means for generating including a reference circuit comprising: a first and a second diode, where said second diode is connected in series with a first resistor, a first amplifier having a positive input connected to said first resistor and a negative input connected to said first diode, said first amplifier having an output outputting a current output, said output being connected to at least a first set of transistors, and a second amplifier having a negative input connected to said first diode and a positive input connected to a second resistor, said second amplifier having an output outputting a current output, said output being connected to at least a second set of transistors; and means for sensing the on-chip temperature of said integrated circuit chip by utilizing at least said reference parameter, wherein said current output of said first amplifier is mirrored and multiplied by a ratio of about Wi/Wo, where Wi corresponds to the width of one of four transistors of said means for sensing the on-chip temperature and Wo corresponds to the width of said at least said first set of transistors.
