Temperature compensation attenuator, amplifier and control method of temperature compensation attenuator

The invention is suitable for the technical field of signal link temperature compensation, and provides a temperature compensation attenuator, an amplifier and a control method of the temperature compensation attenuator. The first end of a first transistor is connected with an input end, and the second end of the first transistor is connected with an output end; the first end of the second transistor is connected with the input end; the second end of the second transistor is grounded; the first end of the third transistor is connected with the output end; the second end of the third transistor is grounded; the first voltage stabilizer provides first gate-source voltage for the first transistor, the second voltage stabilizer provides second gate-source voltage for the second transistor and the third transistor, the first gate-source voltage is in positive correlation with the real-time environment temperature, and the second gate-source voltage is in negative correlation with the real-time environment temperat
