Abstract
A circuit for providing an alternating signal to a switching node. The circuit includes three power transistors, two capacitors, and two gate drivers. The first and second transistors are connected in series, with the switching node connected therebetween. When the first transistor is on and the second transistor is off, a high voltage is provided to the switching node via the first transistor. When the first transistor is off and the second transistor is on, a low voltage is provided to the switching node via the second transistor. The transistors are controlled via the gate drivers. Charge is provided to the gate drivers via the capacitors. The capacitors are charged via an intermediate power source, with the third power transistor connected in diode configuration between the two capacitors. The circuit is capable of withstanding high voltage differences across the transistors, and may be implemented monolithically on a same epitaxial stack.
