Радіовимірювальний перетворювач тиску на основі тензочутливих двостокових МДН-транзисторів

Abstract

We have studied the circuit pressure transducer based on field-effect transistors, wherein the pressure transducer acts two drain MOSFET tenzotranzistors. Selfoscillating circuit allows pressure to convert to a frequency output signal, which improves the characteristics of the metrological device. Calculated and analytical expressions for the conversion function and sensitivity functions. Sensitivity of the device is 40-34 kHz/kg/mm2.
