Claim 0:
1. A signal generation circuit, comprising: a switch module, a voltage generation module, and a signal generation module, wherein,
the switch module connected with the voltage generation module comprises at least one control switch, the switch module configured to receive a frequency-divided signal to cause the at least one control switch to open or close based on the frequency-divided signal;
the voltage generation module is respectively connected with the switch module and the signal generation module, configured to generate a first voltage and a second voltage, wherein the at least one control switch controls the first voltage and the second voltage to change;
the signal generation module is connected with the voltage generation module and configured to generate, based on the received first voltage and second voltage, a carrier signal having a frequency consistent with a frequency of the frequency-divided signal.
