Abstract
A voltage providing circuit includes a first voltage output end, a temperature-sensitive element, a power supply circuit and an output circuit. The power supply circuit is configured to apply a control voltage signal to a control end of the temperature-sensitive element. The temperature-sensitive element is configured to, under the control of the control voltage signal, generate a temperature-related voltage, and output the temperature-related voltage via a first end of the temperature-sensitive element, and a value of the temperature-related voltage changes along with an ambient temperature of the temperature-sensitive element. The output circuit is configured to output a temperature-adaptive voltage via the first voltage output end. A difference between a value of the temperature-adaptive voltage and the value of the temperature-related voltage is within a predetermined range.
