Patent ID: 8278950

Claim:
An apparatus comprising: an integrated circuit (IC) including: at least one active device, at least one conductive IC circuit path operably coupled to said at least one active device, at least one IC electrode operably coupled to said at least one conductive IC circuit path for conveying current between an external connection and said at least one active device via said at least one conductive IC circuit path, and voltage measurement circuitry, including a plurality of resistances having substantially equal temperature coefficients, operably coupled between said at least one IC electrode and said at least one active device for measuring at least IC electrode and device voltages at said at least one IC electrode and said at least one active device, respectively, to provide a measured voltage related to a voltage difference between said IC electrode and device voltages; wherein said measured voltage is related to a current flowing between said at least one IC electrode and said at least one active device, and a ratio of said measured voltage and said voltage difference between said IC electrode and device voltages is temperature compensated.
