Abstract
A buffer stage includes a control circuit. The control circuit includes a voltage generator, a voltage-to-current converter, and a current-to-voltage converter. The voltage generator is configured to generate a compensation voltage. The voltage-to-current converter is configured to convert the compensation voltage into a compensation current. The current-to-voltage converter is configured to convert the compensation current into a recovery compensation voltage. The recovery compensation voltage is arranged for modifying an output voltage of the buffer stage.
