A power amplifier circuit includes a circuit topology with first and second switching elements. The first and second switching elements have a closed state and an open state, wherein current flows between the switching elements when they are both in the closed state. The voltage across the first and second switching elements is regulated by a clamping element that sets the connection between the first and second switching elements to a reference voltage when the switching elements are in the off position. The power amplifier may be a switching power amplifier, and the first and second switching elements may be transistors.
