An excitation signal source which is capable of suppressing temperature drifting is designed in this paper. The influence of temperature drifting of the amplifier on the stability and accuracy of data measurements is also studied. The mathematical model on which the design is based is introduced and discussed. The experimental results show that the design is effective in suppressing temperature drifting of the amplifier, therefore it significantly improves the consistency and accuracy of results when it is applied to the application of thickness measurement of PCB copper foil
