Abstract
A switching device may include an input terminal, an output terminal, a primary switching transistor electrically coupled between the input terminal and the output terminal, and a cascode arrangement electrically coupled between the primary switching transistor and the input terminal. The cascode arrangement may include multiple cascode transistors, each having gate terminals coupled to nodes of a voltage divider that is coupled between a positive voltage supply and a reference voltage supply. Emitter-follower bipolar junction transistors (BJTs) may be configured to control voltages at the gate terminals of the primary switching transistor and the cascode transistors to accommodate changes in the output voltage at the output terminal.
