  • Power output stage
    Patent number: 7342448
    Abstract: A class D power output stage for switching a supply voltage comprises a limiting transistor with a controllable path and a control terminal, a complementary limiting transistor with a controllable path and a control terminal, a switching transistor with a controllable path and a control terminal, and a complementary switching transistor with a controllable path and a control terminal. A switched output signal between the controllable paths of the limiting and complementary limiting transistors can be taped off, the controllable paths of the limiting and the complementary limiting transistors are connected together and are connected to a first and a second supply terminal via the controllable paths of the switching and complementary switching transistors, and the switching and the complementary switching transistors have a lower electrical strength than the limiting and complementary limiting transistors.
    Type: Grant
