Abstract:
1. A voltage-temperature sensor, comprising: a first converter configured to generate a first digital data based on an operational voltage and an operational temperature, wherein the first converter has a first sensitivity to the operational voltage and the operational temperature; a second converter configured to generate a second digital data based on the operational voltage and the operational temperature, wherein the second converter has a second sensitivity to the operational voltage and the operational temperature, and the second sensitivity is different from the first sensitivity; and a data processing block configured to determine and output a combination of an unknown value of the operational voltage and an unknown value of the operational temperature based on a combination of the first digital data and the second digital data, wherein each of the first converter and the second converter is a time-to-digital converter configured to respectively generate a detection signal, the detection signals have temporal characteristics based on the operational voltage and the operational temperature, and the first digital data and the second digital data are generated based on the detection signals.
