本站原创【摘 要 】针对工程设计及硅微机械陀螺的技术要求,在原有的陀螺输出信号的基础上零位偏置,由双极性陀螺信号变为单极性陀螺信号,并把应用环境中的+12V单电源供电设计成正负双电源供电.根据传递函数,设计了电路,对电路进行了Pspice仿真,仿真结果显示电路设计正确,最后设计了PCB,经测试符合技术要求.
【关 键 词 】硅微机械陀螺,偏置电路,Pspice,PCB
Abstract：To meet the need of engineering design and technical requirements of silicon microgyroscope,a new design has been made to offset the zero position from bipolar signal to unipolar signal.The +12V single power supply has been made to ±12V double power supply.According to the traner function,circuit has been designed and Pspice simulation has been made.The simulation result shows that the design is correct.PCB has been produced and meets the demands after measurement.
Key words：silicon microgyroscope,bias circuit,Pspice,PCB
