Claim 1
Independent Claim
62 words
AN INTEGRATED ELECTRICAL CIRCUIT INCLUDING A PLURALITY OF INSULATED-GATE FIELD-EFFECT TRANSISTORS EACH HAVING SOURCE, DRAIN AND GATE ELECTRODES FORMED ON A SINGLE SUBSTRATE OF SEMICONDUCTOR MATERIAL COMPRISING: MEANS FOR BIASING SAID SUBSTRATE TO A POTENTIAL WITH RESPECT TO SAID SOURCE ELECTRODE TO REDUCE THE SOURCETO-DRAIN CURRENT TO SUBSTANTIALLY ZERO IN THE ABSENCE OF INPUT SIGNALS APPLIED BETWEEN SAID GATE AND SOURCE ELECTRODES.
