Nanoelectronic Pressure Transducer with a Frequency Output Based on a Resonance Tunnel Diode

Abstract

The report shows the possibility of creating a nanoelectronic transducer with a frequency output based on a tunnel resonance diode. The electrical circuit of the nanoelectronic pressure transducer consists of a constant voltage source that feeds the tunnel resonance diode and a circuit of two bipolar transistors, three resistors, inductance and capacitance. The circuit implements a self-oscillator whose frequency depends on the action of pressure. Under the action of pressure on the tunnel resonance diode its voltage changes, that leads to a change in negative differential resistance in the oscillatory system of the oscillator, which in turn changes the output frequency of the oscillator. As shown by experimental studies, the sensitivity of the transducer was 0.25-2.25 kHz/kPa. A mathematical analysis of the operation of the circuit is carried out.
