| Abstract(in English) | The author has recently dared to establish a novel hypothetical theory that the operation of the bipolar junction transistor can be explained by the light emission and the photovoltaic effect at the PN and NP junctions in the transistor. On the basis of this new hypothesis, he invented a novel amplifier consists of an infrared LED and a silicon photodiode excluding any transistor. The author named this original amplifier "DISTAR". Using the DISTAR, we can design various "transistorless" amplifiers. This paper describes the new theory on the operation of junction transistor and introduces a practical voltage amplifier with G(gain)>40dB using the DISTAR. |
