Abstract: In an integrated circuit, a bootstrapped switch includes a capacitor and first, second, and third transistors. The first transistor has a first current electrode coupled to a first voltage supply node and a gate electrode coupled to a first circuit node. The second transistor has a first current electrode coupled to a second voltage supply terminal, a second current electrode coupled to a top terminal of the capacitor, and a control electrode coupled to the first circuit node. The third transistor has a first current electrode coupled to the first voltage supply terminal, a control electrode coupled to the first circuit node, and a second current electrode coupled to a body terminal of the second transistor. The fourth transistor has a first current electrode coupled to the body terminal of the second transistor, and a second current electrode coupled to the top terminal of the capacitor.
