How Do Transistors Work Anyway Lcamtuf S Thing [johnaudiotech] takes a decidedly practical approach to jfets in a recent video that you can watch below. Junction field effect transistors (jfets) remain a cornerstone in analog circuit design, offering exceptional input impedance, low noise, and reliable performance across a wide range of applications.
5 Applications Of Jfet Transistors Interfet Unlike bipolar junction transistors (bjts), which are controlled by current, jfets are voltage controlled devices. this characteristic endows jfets with high input impedance and low noise, making them ideal for specific applications such as amplifiers and signal processors. We tend to think that jfets are optimised for high impedances, but even with low impedances (as low as 100Ω or so), jfets can beat bipolar transistors. noise is (usually) minimised by operating a jfet with zero gate voltage (and therefore maximum drain current), but this is not always feasible. There are two basic configurations of junction field effect transistor, the n channel jfet and the p channel jfet. the n channel jfet’s channel is doped with donor impurities meaning that the flow of current through the channel is negative (hence the term n channel) in the form of electrons.

The early germanium transistors weren't really good. neither their amplification factor, nor their curve on the oscillogramme. also, there existed good radio tubes at the time made for the car.
