Patent ID: 8344789

Claim:
An analog switch, comprising: a first switch device cluster having current terminals coupled between input and output nodes, having a first control terminal controlled by a control input, and having a first body junction, wherein said first switch device cluster comprises: a first device of a first conductivity type having a first current terminal coupled to said input node, having a second current terminal coupled to said output node, having a control terminal receiving an inverted control signal, and having said first body junction; a second device of said first conductivity type having a first current terminal coupled to said input node, having a second current terminal coupled to said first body junction, having a control terminal receiving said inverted control signal, and having a body coupled to said first body junction; and a third device of said first conductivity type having a first current terminal coupled to said output node, having a second current terminal coupled to said first body junction, having a control terminal receiving said inverted control signal, and having a body coupled to said first body junction; a second switch device cluster having current terminals coupled between said input and output nodes, having a second control terminal controlled by said control input, and having a second body junction, wherein said first switch device cluster comprises: a first device of a second conductivity type having a first current terminal coupled to said input node, having a second current terminal coupled to said output node, having a control terminal receiving a non-inverted control signal, and having said second body junction; a second device of said second conductivity type having a first current terminal coupled to said input node, having a second current terminal coupled to said second body junction, having a control terminal receiving said non-inverted control signal, and having a body coupled to said second body junction; and a third device of said second conductivity type having a first current terminal coupled to said output node, having a second current terminal coupled to said second body junction, having a control terminal receiving said non-inverted control signal, and having a body coupled to said second body junction; a plurality of first body control devices, each having a first current terminal coupled to one of said input and output nodes, each having a control terminal coupled to the other one of said input and output nodes, and each having a second current terminal coupled to said first body junction of said first switch device cluster; and a plurality of second body control devices, each having a first current terminal coupled to one of said input and output nodes, each having a control terminal coupled to the other one of said input and output nodes, and each having a second current terminal coupled to said second body junction of said second switch device cluster.
