Abstract
A clock generation circuit includes a reference voltage generator configured to generate a first current having a current value inversely proportional to a reference voltage and a temperature, a bias circuit configured to generate a bias current, a second current having a current value proportional to the temperature, and a third current based on the reference voltage, a voltage generator configured to generate a supply voltage based on the first current, the bias current, and the second current, and an oscillation circuit configured to generate a clock signal having a constant frequency based on the supply voltage and the third current, wherein the supply voltage is generated to have a slope based on a ratio of the first current to the second current.
