Electronic circuit element with field-effect transistor operation applications of this circuit element, and substitution circuit for such an element

摘要

An electronic circuit element with field-effect operation and with such characteristics that its source terminal (2) is to be connected, in the case of an N-type element (1a) to the positive, and in the case of a P-type element (1b) to the negative pole of a current source, said element (1) being non-conducting if its gate terminal is at the voltage of the pole connected with the drain terminal (3). This element (1) can be used as a memory circuit, for forming a trivalent switching circuit, and as an analogue amplifier with a negative resistance characteristic. Such an element (1) can be assembled from a series connection of an n- type and a p-type field-effect transistor (11a, 11b) having their source electrodes (12) interconnected, the gate terminal (4) being formed by the gate electrode (14) of the n-type or p-type transistor (11a, 11b) resp., the gate electrode (14) of the other transistor being connected with the drain electrode (13) of the first one.
