Claim 2:
3. The control amplifying circuit of claim 2, wherein the preset voltage values comprise a first voltage value and a second voltage value, and the power supply output circuit is further configured to:
select the first voltage value to output as the preset power supply signal when the first power supply switching signal is in a first level state and the second power supply switching signal is in a second level state; or
select the second voltage value to output as the preset power supply signal when the first power supply switching signal is in the second level state and the second power supply switching signal is in the first level state;
wherein the first voltage value and the second voltage value both belong to the second level state, and the first voltage value is greater than the second voltage value.
