Abstract: Aspects of the disclosure provide for a circuit. In some examples, the circuit includes a first transistor, a second transistor, a third transistor, a first capacitor, and a second capacitor. The first transistor comprises a drain terminal coupled to an input voltage node, a source terminal coupled to a first node, and a gate terminal coupled to a second node. The second transistor comprises a drain terminal coupled to a third node, a source terminal coupled to a fourth node, and a gate terminal coupled to a fifth node. The third transistor comprises a drain terminal coupled to a sixth node, a source terminal configured to couple to a gate terminal of a switching transistor, and a gate terminal coupled to a seventh node. The first capacitor is coupled between the first node and the third node. The second capacitor is coupled between the fourth node and the sixth node.
