Abstract

We investigate the current-voltage (I-V) curves of the p-n junctions in 2N3904 npn and 2N3906 pnp bipolar junction transistors as the frequency of a triangular input voltage is increased. Frequency dependent hysteresis on I-V curves was observed. The p-n junction capacitance was also measured by obtaining the charging and discharging plots at increasing frequency. We found that the driving frequency can enhance the hysteresis of the diode, and the capacitance of the p-n junction exhibited direct dependence on the applied bias voltage.
