Abstract
The present disclosure relates to a voltage reference generator without temperature dependency. The disclosed voltage reference generator includes a precursor voltage generator and a voltage extractor. The precursor voltage generator is configured to provide a base-emitter voltage, a proportional-to-absolute-temperature (PTAT) voltage, and a nonlinear (NL) voltage. The voltage extractor is configured to scale and sum the base-emitter voltage, the NL voltage, and the PTAT voltage and provide an output voltage, such that linear temperature dependent components and nonlinear temperature dependent components within the base-emitter voltage, the NL voltage, and the PTAT voltage are not included in the output voltage, which is temperature independent.
