JFETs – The Dirty Details (3/3): Practice 2

JFET as voltage controlled resistors, amplifiers and constant current sources … ↓↓↓ Complete description, time index and links below ↓↓↓ In the last video we used a J176 P-channel JFET as a high/low side DC switch – at which it sucked – and as an AC signal switch – at which it excelled (link below). Now we’ll explore some more JFET circuits. First we have a look at the ohmic of the characteristic curve. Then we build a voltage controlled resistor and an amplifier. After that we have a look at the saturation region. Towards the end we build two different constant current sources. 00:00 Intro – even more JFET circuits 00:55 Ohmic region – characteristic curve 04:58 Voltage controlled resistor – attenuating 12:37 Amplifier – high impedance inputs 20:39 Saturation region – characteristic curve 23:22 Constant current sources – the simplest 29:57 Wrap-up – that’s it for today, bye Tutorials:    • Tutorials   JFETs – The Dirty Details (1/3): Theory    • JFETs – The Dirty Details (1/3): Theory   JFETs – The Dirty Details (2/3): Practice 1    • JFETs – The Dirty Details (2/3): Practice 1   #jfet #tutorials #tutorial #robertssmorgasbord
