Abstract
A push-pull driver according to an example includes a push stage coupled via a first coupling capacitor to an output of the push-pull driver and a pull stage coupled via a second coupling capacitor to the output of the push-pull driver. Using an example may allow to improve a trade-off between saving energy, an overall complexity of a corresponding implementation, a robust and reliable operation and other parameters and design goals.
