Semiconductor-free electric and electronic circuit components

Abstract

With this invention, electronic circuit components such as transistors, diodes, zener diodes and varicap diodes, which are conventionally manufactured with semiconductors, can be produced without semiconductors by means of a much simpler and cheaper technology, and by the same technology a compensation capacitor can be manufactured whose capacitance is automatically varied so as to follow changes in the load simultaneously. This principle may also be applied in other areas such as microwaves. In simple terms, the electric and magnetic fields of the main capacitor are blocked by a control voltage and varied between zero and maximum values, and as a result the capacitance of the main capacitor is changed. The fundamental principle here is the control of the electric and magnetic fields between the two conductive plates of a fixed-capacitance capacitor. For this purpose, a control voltage is applied between a third metallic plate, designed as a grid or similar structure so as not to block the electric and magnetic fields of the main capacitor and placed closer to one of the two plates, and the adjacent metallic plate, while a DC voltage (VDD) of suitable value for the circuit is applied across the terminals of the main capacitor. In a slightly different version, two grids are provided so that the structure can be used both as a diode and as a transistor. In both cases, the capacitance value of the main capacitor varies depending on the control voltage, i.e. Co = f(Vi). This means that, similar to classical transistors, the impedance of the circuit varies depending on the control voltage. In this structure, which exhibits behaviour similar to FET transistors, the output voltage is taken across the two outer plates of the capacitor with a design similar to a classical transistor circuit. In the production stage, the dielectric will be formed by coating very thin special plastic or other suitable materials with an appropriate metal of suitable thickness for the design and winding it in roll form. Likewise, dielectric layers may also be formed as very thin oxide or other non-conductive chemical compounds on the surfaces of the metallic 24 plates. That is, use will be made of conventional capacitor technologies such as ceramic, tantalum and electrolytic capacitors. In addition, different methods may be developed depending on the field of application. These designs will find application areas as semiconductor-free transistors, diodes, voltage-controlled variable capacitors, and many other uses, some of which have been explained in this project.
