Abstract
A switch arrangement for providing a drive signal at an output comprises a drive switch coupled to the output of the switch arrangement and a regulating element coupled in series between the drive switch and a power supply input of the switch arrangement. The drive switch is operable to provide the drive signal at the output. The switch arrangement is characterized in that the regulating element is coupled in a cascode arrangement with the drive switch such that in operation the regulating element limits the voltage drop across the drive switch to a predetermined level.
