| 摘 要： | 传统的微陀螺转子驱动电路采用对模拟信号直接移相实现,为了解决模拟信号直接移相时移相范围有限、调试复杂等不足,设计出了基于FPGA的数字式驱动微陀螺旋转移相电路。通过FPGA产生相位差信号,经D/A转换电路和巴特沃兹滤波电路处理后输出信号。该数字式移相方法产生的信号的相位差（0°～360°）、频率均可调,为涡流旋转微陀螺转子提供了理想的信号源。

| Abstract: | Traditional drive circuit of micro-gyroscope rotor is based on direct phase-shift of analog signal to overcome the drawback of direct phase shift of analog signal, such as limited phase-shift in scope, complex debugging, etc. In this paper, a phase-shifting circuit of micro-gyroscope-driven rotating based on FPGA is designed. The phase difference signals are generated by FPGA, then they are output after processing by D / A converter circuit and the Butterworth filter circuit. The phase difference(0°-360°) and frequency of the signals generated by the digital phase shift method are adjustable. It provides a good signal generator for rotating micro-gyroscope rotor. |
