More Information
Summary:The embodiment of the invention provides an oscillation circuit and a clock generation circuit, and the oscillation circuit comprises a power generation module which is configured to generate a positive temperature coefficient voltage based on a positive temperature coefficient current; the positive temperature coefficient voltage is used as a power supply of the oscillator; the oscillator comprises a first ring topological structure which is formed by connecting a plurality of first phase inverters end to end and propagates oscillation signals at a first transmission speed; the second ring topological structure is formed by connecting a plurality of second phase inverters end to end and propagates the oscillation signal at a second transmission speed; wherein the first ring topological structure is electrically connected with the second ring topological structure, and the second transmission speed is smaller than the first transmission speed. The embodiment of the invention is favorable for improving the sta
