ABSTRACT:
A pulse amplifier implemented in standard CMOS, comprises a control circuit for controlling a driver stage for driving a class D output stage that comprises a first PMOS-transistor and a first NMOS-transistor with interconnected drain contacts. A driver stage comprises a first driver and a second driver coupled with the output stage. Furthermore, a second NMOS transistor and second to fifth PMOS transistors are provided and interconnected in a way that most of the control signals needed to switch the high voltage output, specifically the drivers, are generated within a low voltage block. These factors contribute to lowering the total power dissipation.
