Abstract: First and second circuit branches are coupled between an input node and ground. Each circuit branch includes a series coupling first-fourth transistors in a current flow path with an output node. A first capacitor is coupled between a first capacitor node and a second capacitor node intermediate the first transistor and the second transistor in the first circuit branch. A second capacitor is coupled between a third capacitor node and a fourth capacitor node intermediate the first transistor and the second transistor in the second circuit branch. An inter-branch circuit block between the first and second branches includes a first inter-branch transistor coupled between the first capacitor node in the first circuit branch and the fourth capacitor node in the second circuit branch and a second inter-branch transistor coupled between the third capacitor node in the second circuit branch and the second capacitor node in the first circuit branch.
