Kalinina L. N., A. Litvinov V., Nikolaev I. N.The particular of the MIS-sensors dynamic characteristics

 

This paper deals with the particular of dynamic characteristics, which was found on some type of the MIS-sensors. This particular consist in crossing through zero of the sensors signal during relaxation (after removal gas) and the sensors signal remain negative during long time. This phenomenon introduces relatively small error in measurements of gas concentration, therefore it can be neglect. However founded effect can be of interest for creation microscopical theory of trap centers, which are responsible for sensitivity to gases of the MIS-sensors.

Keywords: MIS-sensor, dynamic characteristic of MIS-sensors.

 

 

Ignateva E. V., Mikhailov Yu. A., Pankov V. V. On the sensitivity increase of silicon pressure strain transducers

 

The traditional methods of sensitivity increase are accompanied by increase of nonlinearity of the converting characteristic that limits their capabilities. The new membrane design optimization enabled to reach sensitivity more than 7 mV/V∙kPa with simultaneous decrease of nonlinearity. The nominal pressure of the strain transducer was decreased till 1 kPa.

Keywords: integrated silicon pressure transducer, nonlinearity of transforming characteristic, design sensitivity factor.
