Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
astable multivibrator aimed to be fed by a photovoltaic
cell, with the purpose of energy harvesting for electronic
systems. The circuit was simulated using metal-oxide
semiconductor field effect transistors (MOSFETs) and
bipolar junction transistors. The use of half-wave and
full-wave rectifiers for DC output voltage supply was
also analyzed. The circuit reached a peak efficiency of
28 % when using MOSFETs PMDXB550UNE and half wave rectifier.
