Abstract
An oscillation circuit includes: a power supply generation module and an oscillator. The power supply generation module is configured to generate a positive temperature coefficient voltage based on a positive temperature coefficient current; and the positive temperature coefficient voltage serves as a power supply of the oscillator. The oscillator includes: a first ring topological structure and a second ring topological structure. The first ring topological structure is formed by a plurality of first inverters connected end to end and configured to transmit an oscillation signal at a first transmission speed; and the second ring topological structure is formed by a plurality of second inverters connected end to end and configured to transmit the oscillation signal at a second transmission speed. The first ring topological structure is electrically connected with the second ring topological structure, and the second transmission speed is less than the first transmission speed.
