FIELD EFFECT TRANSISTOR AMPLIFIER/ AC SIGNAL
FET Amplifiers provide an excellent
voltage gain with the added feature of
a high input impedance.
Its Configuration low power consuming

There are a number of different electronic devices which tend to be called diodes.
Although they're made differently they all have three things in common.
They have two leads like a resistor.
The current they pass depends upon the voltage between the le
Junction field effect transistors (JFETs) come in two 'flavours', p-channel and n-channel. In each case a
bar, or channel, of one type of semiconductor material is located inside a bulk material of the other kind
i.e. p inside n, or n inside p. The explan
The behaviour of a JFET can be described in terms of a set of Characteristic Curves.
In the region shown with a green background the drain-source voltage is small and the
channel behaves like a fairly ordinary conductor. In this region the current varies
