Zusammenfassung: | In this paper, an analog circuit design for the precision reading circuit of the tactical grade accelerometer is presented. Quartz accelerometer is modeled mathematically by dividing its structure into subunits. This model has been transferred to MATLAB-SIMULINK environment to observe the effects of some parameter changes on the model. In the light of the studies that exist in literature, open and closed loop circuit models are emphasized and the ideal design has been formed by working on many design models such as voltage frequency conversion or Σ-Δ transformation. The effects of the components and other sources of noise are taken into account in the simulation in order to ensure that the simulation is compatible with the actual conditions. Optimal circuit structure has been reached in the studies conducted within the scope of this model and this circuit has been transferred to a prototype. In the light of prepared models, the final structure of the circuit is revealed and this structure is first implemented on the schematic and then on the printed circuit board. In the laboratory environment, the test circuit is tried and tested. By comparing the obtained measurements and simulation results, the comparison of production and design objectives are evaluated. |
