Forming structure of an integral analog front-end for smart vibration sensor
Incoming article date: 15.06.2015Today developing specialized microelectronics in Russia is an actual problem because many components are absent on the open market, and also because import substitution is a vital task. One can’t make front-end products just by copying, new electronic components must be developed. These components needed in real production sector of economics. One must be aware that to develop the product with competitive ability only some universal scheme must be realized. Nowadays the market is being overpopulated by different smart sensors: temperature, gas, ph-metering. These products are used in different sectors of economics from smart houses making to heavy machinery production. World market has specialized electronics for signal conditioning called analog front-end (AFE). Usage of these components allow to make end-products of significantly smaller size, and also to make their self-cost lower. Smart vibration sensors do not have its AFEs today, so the problem of minimizing their size is not solved. To develop such electronics one need to form a basic structure of AFE suitable for all vibration measurement. For the basis for this structure can be used the structure of a sensor itself, and products already put to market could be used for an example of such electronics. There are certain differences between present AFEs and needed ones for smart vibration sensors. Most of differences concentrated in the input schemes and ADC.
