Pressure transducer of the on the basis of reactive properties of transistor structure with negative resistance

The opportunity of direct transformation of pressure in frequency is shown on the basis of the hybrid integrated circuit consisting of the two-collector pressure sensitive transistor and the field two-gate transistor with an active inductive element on the basis of the bipolar transistor with a phase-shifting RC chain. Analytical dependencies of transformation function and the equation of sensitivity are received. Theoretical and experimental research have shown, that sensitivity of the transducer makes 1,55-1,10kHz/kPa.
