COMPENSATION OF THERMALLY INDUCED VOLTAGE ERRORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522321 titled 'COMPENSATION OF THERMALLY INDUCED VOLTAGE ERRORS
Simplified Explanation
The integrated circuit described in the abstract is designed for temperature gradient compensation of a bandgap voltage. Here are some key points to explain the patent/innovation:

Original Abstract Submitted
Described embodiments include an integrated circuit for temperature gradient compensation of a bandgap voltage. A bandgap core circuit has a bandgap feedback input, a bandgap adjustment input and a bandgap reference output. A resistor is coupled between the bandgap adjustment input and a ground terminal. An offset and slope correction circuit has an offset correction output that is coupled to the bandgap adjustment input. A signal at the offset correction output is trimmed at an ambient temperature. A thermal error cancellation (TEC) circuit has a TEC output coupled to the bandgap adjustment input. The TEC circuit includes first and second temperature sensors that are located apart from each other. A signal at the TEC output is responsive to temperatures at the first and second temperature sensors. An amplifier has an amplifier input and an amplifier output. The amplifier input is coupled to the bandgap reference output.
