Abstract
Provided are a chip power supply circuit and an electronic device, which relate to the field of power supply technologies. The chip power supply circuit includes: at least two chip domains, where the at least two chip domains are sequentially connected, and in two adjacent chip domains, a ground port of a previous-stage chip domain is connected to a primary power supply port of a next-stage chip domain; and at least one voltage conversion circuit, where in the two adjacent chip domains, the ground port of the previous-stage chip domain is connected to a secondary power supply port of the next-stage chip domain through a voltage conversion circuit of the at least one voltage conversion circuit, and the voltage conversion circuit is configured to output a target voltage to the secondary power supply port.
