Abstract
In order to meet the requirements of mid-infrared gas detection, a high-precision DSP lock-in amplifier is designed with MATLAB/Simulink and DSP. By using Target for TI C2000 toolbox which integrates Simulink with TMS320F2812, the automatic generation of C code can be achieved and the programming time can be saved enormously. An AD correction module is added in this paper to ensure sampling accuracy. The high-precision lock-in amplifier design is implemented skillfully by modularized design in Simulink. The experimental results show that the designed DSP Lock-in Amplifier possesses low error(<0.5%) and high stability.
