Title: Gerhard Krumrein: Innovator in Amplification and Protection Circuits
Introduction
Gerhard Krumrein is a notable inventor based in Neuenstadt, Germany. He holds a total of seven patents, showcasing his contributions to the fields of electronics and circuit design. His innovative work has significantly impacted the development of amplification and protection circuits.
Latest Patents
One of Krumrein's latest patents is a broad-band amplifier designed for the amplification of a photoelectric current triggered by a light signal. This amplifier includes a first transistor that receives the photoelectric current, a second transistor connected in series with the first, and a resistance that connects the base of the first transistor to the emitter of the second. Additionally, it features a current mirror formed by a third and fourth transistor, with the third transistor connected in series with the second. A resistance is also located between the third transistor and ground. Another significant patent is a protection circuit for integrated circuits. This circuit is connected across a power source and includes a first transistor and a zener diode or equivalent circuit arrangement. This setup causes the first transistor to conduct if the integrated circuit receives excessive voltage from the power source. A measuring resistor connected to the emitter of the first transistor allows for voltage drop measurement, while a comparator compares this voltage to a reference voltage.
