In this paper we propose a new method for constructing the magnetic field of frequency transducers based on magnetically effect in bipolar transistors. Circuits of the magnetic field of frequency transducers on the single and the two-collectors bipolar transistors have been offered, which sensitivity is here from 0.5 to 7 kHz/mT.
In the article the pressure transducer with frequency output based on the structure of the bipolar-field transistors with negative resistance and tenso sensitive MEMS capacitor has been considered. A mathematical model of the radiomeasuring pressure transducer in dynamic regime has been developed that allowed to determine the voltage or current in the circuit at any given moment in time when acting...
The experimental research of characteristics of the microwave oscillator based on the structure of static inductance transistor has been carried out and the model of its static and dynamic current-voltage characteristics has been improved. The results of the experimental research show that oscillating frequency changes from 770 to 900MHz, amplitude of generate oscillations changes from 5 to 22 V,...
