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.
