Zusammenfassung:Certain aspects of the present disclosure are directed to a circuit for driving a signal at an output node. The circuit generally includes a voltage divider network having a first terminal coupled to the output node. The circuit also includes a first transistor having a gate coupled to a second terminal of the voltage divider network and a plurality of transistors. A gate of each of the plurality of transistors may be coupled to a respective tap node of the voltage divider network, and the plurality of transistors may include a third transistor having a source coupled to a drain of the first transistor. The circuit may also include a second transistor coupled to the first transistor and having a gate coupled to an input node of the circuit.
