Circuit for biasing a bulk terminal of a MOS transistor

摘要

A circuit for biasing the bulk terminal of a first MOS transistor having a first terminal connected to a first line set to a first potential, and a second terminal connected to a second line set to a second potential. The biasing circuit includes a second and a third MOS transistors having first terminals connected respectively to the first line and to the second line, second terminals connected to the bulk terminal of the first MOS transistor, and control terminals connected respectively to the second and to the first line.
