  • a silicon thermal astable multivibrator for flow and temperature sensing
    IEEE Transactions on Electron Devices, 2002
    Co-Authors: Sisira K Gamage, Nihat Okulan, H T Henderson
    Abstract:

    Here we report for the first time on a thermal astable multivibrator modality made possible with a silicon bulk micromachined flow sensor. The sensor shows an oscillatory response for constant current input. Further, the frequency of oscillation is modulated with the temperature of the sensing element, realizing the performance of a thermal multivibrator. The temperature variation is induced via air flow and a change in frequency of 5 Hz is observed for air flow velocities in the range of 0-21 m/s. The low output frequencies (20-25 Hz) observed clearly suggest that the oscillations are purely thermal in origin. In contrast, others have reported many electronic switching effects obtained by the various physical mechanisms via negative differential resistance regimes, which typically give rise to much higher frequencies of oscillations in the range of kHz-GHz.

  • Pembuatan Trainer Board Astable Multivibrator (AM) sebagai Media Pembelajaran
    Universitas Andalas, 2016
    Co-Authors: Syifaul Fuada
    Abstract:

    Trainer board is a modelling device approach which has related function or same with real pheneonom, it was designed for upgrading the cognitive and the psychomotoric ability of students in a practical courses understanding and applicating concepts. This research goals is to make a trainer board of Astable Multivibrator oscillator, we hope that this learning tools can help them in facilitate to learn Astable Multivibrator characteristics as well as laboratories insfrastructure need. The method in design and implement this trainer board is prototyping and assembling with several approach steps, i.e. identification; simulation; experiment, design process; fabrication; and finally is testing. The results show that the trainer board which designed is appropriate with the theorem
