AB  - This paper presents a novel digital miniaturization method for a prototype 
      silicon micro-gyroscope (SMG) with the symmetrical and decoupled structure. The 
      schematic blocks of the overall system consist of high precision analog front-end 
      interface, high-speed 18-bit analog to digital convertor, a high-performance core 
      Field Programmable Gate Array (FPGA) chip and other peripherals such as 
      high-speed serial ports for transmitting data. In drive mode, the closed-loop 
      drive circuit are implemented by automatic gain control (AGC) loop and software 
      phase-locked loop (SPLL) based on the Coordinated Rotation Digital Computer 
      (CORDIC) algorithm. Meanwhile, the sense demodulation module based on varying 
      step least mean square demodulation (LMSD) are addressed in detail. All kinds of 
      algorithms are simulated by Simulink and DSPbuilder tools, which is in good 
      agreement with the theoretical design. The experimental results have fully 
      demonstrated the stability and flexibility of the system.
