Claim 5:
6. The signal generation circuit according to claim 1, wherein the signal generation module comprises a capacitor, a first branch circuit, a second branch circuit, and a comparison unit;
the comparison unit respectively connected with the voltage generation module and the capacitor is configured to receive the first voltage and the second voltage, output a first feedback signal with a first level to the first branch circuit based on a voltage of the capacitor smaller than the second voltage, and output to the second branch circuit the first feedback signal with the first level based on a voltage of the capacitor larger than a voltage of the first feedback signal;
the first branch circuit is connected with the capacitor and configured to charge the capacitor based on the first feedback signal with the first level;
the second branch circuit is connected with the capacitor and configured to cause the capacitor to discharge based on the second feedback signal with the first level;
the capacitor is respectively connected with the first branch circuit and the second branch circuit, and configured to generate the carrier signal at a connecting terminal connected with the first branch circuit and the second branch circuit.
