What is a JFET and how does it work?

JFETs are not as popular as their cousin, the MOSFET, but they're still important enough that we wanted to discuss what a JFET is and go into the details of how it works. In this tutorial, Josh reviews the symbol of JFET, operating principles of a FET in general, the internal construction of a JFET, before very briefly touching on JFETs versus MOSFETs. This high-level overview is helpful for anyone trying to get a basic idea of JFETs and the benefits and drawbacks of their use. We always highly recommend also reading the written tutorial, which can be found here: https://www.circuitbread.com/ee-faq/j...
