Abstract
A power supply circuit and a chip to which the power supply circuit is applied are disclosed. The power supply circuit includes a constant current generation circuit and a voltage generation circuit. The constant current generation circuit is configured to generate a first current with a positive temperature coefficient and a second current with a negative temperature coefficient, and generate a constant current according to the first current and the second current. The voltage generation circuit includes a transistor, is coupled to the constant current generation circuit, and configured to generate a temperature-dependent voltage according to the constant current and characteristics of the transistor.
