Field-effect transistor amplifier

Field-effect transistor amplifier

Field-effect transistors are widely used since they have an input impedance higher than that of bipolar transistors, the output impedance is lower, with better temperature stabilization and radiation resistance.
The construction of amplifiers on field-effect transistors is the same as that of amplifiers on TTOs.

Field-effect transistor amplifier with a common source circuit


R3 - a resistor that provides a negative potential with respect to the source to the gate. Rз = (0,1-0,03) Rzu DC

Amplifier parameters



Ri is the internal resistance of the field effect transistor.
