Abstract
The present invention provides a switch circuit having a switch and a first body grabbing circuit. The switch includes a first transistor and a second transistor. The first transistor has a body and is coupled to the second transistor in parallel to form a common source and a common drain. The common source defines an input node and the common drain defines an output node. The first body grabbing circuit is coupled to the body of the first transistor. The first body grabbing circuit is arranged to couple the body of the first transistor to the input node when the first and second transistors receive a turn-on voltage signal such that a body effect is eliminated in the first transistor.
