Abstract: Aspects of the disclosure provide for a method. In some examples, the method includes detecting a transition in an input signal (IN), generating a bias current based on the detected transition in IN, and modifying a charge status of a capacitor based on the charge current. The method further includes generating an output signal (OUT) based on the charge status of the capacitor, disabling the bias current generation based on values of IN and OUT, and strongly pulling the capacitor up or down based on the disabling the bias current generation.
