ABSTRACT:
in a semiconductor array having a tetrode integrated in a semiconductor element, the tetrode comprises two field-effect transistors having a common semiconductor area forming the drain electrode of the first field-effect transistor and the source electrode of the second field-effect transistor. The semiconductor array has a three-pole array integrated in the semiconductor element and functioning as a feedback element, the input of the array is connected to the common semiconductor area of the tetrode. The output of the three-pole array is connected to the semiconductor area forming the gate electrode of the first field-effect transistor of the tetrode.
