Abstract
Provided are a reference source circuit, a chip, a power supply, and an electronic device. The circuit comprises: a first current generation unit used for generating first current; a reference voltage generation unit electrically connected to the first current generation unit and used for generating a band-gap reference voltage by using the first current; and a reference current generation unit electrically connected to the first current generation unit and the reference voltage generation unit and used for generating band-gap reference current by using the first current. By means of the circuit above, a band-gap reference voltage and band-gap reference current can be generated in a reference source circuit, and the first current generation unit may be reused, so that high-gain and simultaneous work of two loops can be achieved, the cost can be reduced, and the chip area can be saved as compared with the design of two separate reference sources.
