Germanium Transistor Temperature

Not dynamically as you suggested but i think the diode acts to stop the increase in collectorbase leakage that exceeds the forward voltage drop of the diode. It states that the diode must have the same temperature dependance as the transistor which i guess would mean doubling leakage with every 10c.

Individual electrical component speed adds up as an aggregate and therefore a germanium transistor array can significantly increase the processing speed of a circuit.

Germanium transistor temperature. Incidentally when measuring germanium transistors they are incredibly temperature sensitve just holding them between the fingers to plug them in to a tester is enough to warm them and it then takes a couple of minutes for the readings to settle down. Germanium transistor temperature sensitivity video showing the leakage current of a germanium transistor varying with temperature changes. But adding germanium to the channeleven initially mixed in with siliconis a solution that will allow chipmakers to keep improving transistors in the near term.

There are ways to improve the temp stabilty of ge by pairing a ge transistor with a ge diode for instance or using one ss transistor and one ge transistor in the fuzz face. Of these 76 ge is very slightly radioactive decaying by double beta decay with a half life of 178 1021 years. Looking at the formula in that article ichfei hfei0 hfe1ic0 i would say that you would also want a germanium diode with about.

74 ge is the most common isotope having a natural abundance of approximately 36. A germanium transistor is a variation on a standard transistor built on the element silicon where instead a silicon silicon germanium alloy is commonly used to increase transmission speed of electrical signals. Germanium occurs in 5 natural isotopes.

Here a small current can be used to control a larger one amplifying a signal or acting as a switch. Germanium transistors were very common but now have been replaced by silicon. But i dont suppose that entirely solves the problem of rising ambient temp raising the hfe of germanium transistors.

Ge electronics arent damaged by summer heat they just react strangely. 70 ge 72 ge 73 ge 74 ge and 76 ge. Once the temperature drops back to the 70s they go back to being stable.

Germanium really took off with the development of the transistor a solid state version of the triode valve. I think thats how it works anyway. Ill have to think about this.
