Abstract
An output buffer includes an output stage formed by a pull-up transistor and a pull-down transistor connected in series between a supply line set at a supply potential and a ground line set at a ground potential. The output buffer further includes a pre-biasing stage for pre-biasing the control terminal of the pull-up transistor and a pre-biasing stage for pre-biasing the control terminal of the pull-down transistor in order to bring these transistors to the turning-on threshold.
