ABSTRACT:
An electronic switch having a reduced body effect includes first and second switch terminals. A first transistor of a first type has a control terminal, a first substrate coupled to a first voltage level, and first and second drive terminals respectively coupled to the first and second switch terminals. A second transistor of a second type has a control terminal, a second substrate, a first drive terminal coupled to the second substrate and to the first switch terminal, and a second drive terminal. A third transistor of the second type has a control terminal, a third substrate, a first drive terminal coupled to the second drive terminal of the second transistor, and a second drive terminal coupled to the third substrate and to the second switch terminal. A fourth transistor of a first type has a control terminal, a fourth substrate, a first drive terminal coupled to the second drive terminal of the second transistor, and a second drive terminal coupled to the fourth substrate and a first voltage level.
