the sensor signal processing circuit

In recent years , with the continuous development of high technology , the sensor increasingly demanding. To further improve the performance of the sensor , the sensor signal processing circuit , a microprocessor and so on the same silicon integrated to form an integrated intelligent sensor. This is the development direction of modern sensors. Intelligent integrated sensor structures are generally three-dimensional devices, namely the three-dimensional structure. This structure is based on a planar integrated circuit , layer by layer to produce three-dimensional multi-layer circuit direction . It is basically a method of manufacturing an integrated circuit fabrication process used , e.g., photolithography , the silicon oxide film formation, polysilicon is deposited , a laser annealing , the polysilicon into single crystal silicon , forming a PN junction and the like. Is a perspective end device having a multilayer integrated circuit formed on the silicon substrate , i.e. sensitive device , and a circuit chip microcomputer , solar power can be produced thereon , forming an integrated intelligent sensor. This sensor has the human brain combines the features and functions , it not only has a detection function, but also has the function of signal analysis and processing , and ultimately be able to output information in digital form . At the same time , it can automatically be drift, drift , nonlinear corrections. Its intelligent integration density increases constantly improved. In the future, with the progress of science and technology, also developed a multi-functional three-dimensional integrated intelligent sensors . This sensor can be detected , the logic and memory functions are integrated on a single semiconductor chip , while the cooling section can also be produced in a three-dimensional circuit, the Peltier effect of the circuit to be cooled . This versatile artificial intelligence integrated sensor is equivalent to a cell , the more complex functions may be completed , it will add light color for the high-tech development . Due to the integration of intelligent sensor technology is taking off , so it is bound to play an important role in the future of sensor technology , while its market prospect is very broad .
