Novel Opt-coupling Transistor by LED and PD and its Application
Abstract
This paper proposes a novel transistor-like device by the optical coupling
of LED (Light Emitting Diode) and Photodiode. The device that we call “OCT:
Optical Coupling Transistor” shows an amplification function if the Photodiode
current by photo electromotive force is feed backed into the LED, in the
same way as the case of common emitter circuit of the conventional Bipolar
Junction Transistor. In this paper, we present the amplification principle
and its applications by OCT such as audio amplifier and operational amplifier.
