Abstract
A switching circuit comprises a control and bias stage configured for receiving a first input voltage signal, a second input voltage signal and a selection signal and for generating therefrom a first bulk bias signal substantially equal to the first input voltage signal or to the second input voltage signal depending on the selection signal. The switching circuit further comprises a switching stage connected to the control and bias stage, including a transistor having a bulk terminal, and configured for receiving the bulk bias signal and generating an output signal having the first input voltage signal when the selection signal indicates the selection of the first input voltage signal or having the second input voltage signal when the selection signal indicates the selection of the second input voltage signal. The bulk bias signal is electrically coupled to the bulk terminal of the transistor.
