| Abstract: | Integration and digitalization are two key factors leading to the engineering application and batch manufacturing of FOG. By considering the FOG's technical situation and the technique of semiconductor in our country,the research on integration and optimization of digital detecting circuit for the closed loop FOG based on the fast DSP chips and large scale CPLD or FPGA chips is presented in this paper. Test result shows: the performance and reliability of integrated detecting circuit are improved as compared with the circuit based on the separated components. |
