ABSTRACT:
An electronic circuit may comprise an input stage powered by a supply voltage and configured to receive a reference signal. The circuit may further comprise an output stage powered by the supply voltage and coupled to the input stage, and configured to generate an error signal based on: the reference signal, and a feedback signal based on an output signal. The circuit may also include a pass transistor powered by the supply voltage and configured to generate the output signal based on the error signal. A capacitor coupled between the supply voltage and the output stage may increase the current flowing in the output stage, resulting in the output stage conducting current even during a rising edge of the supply voltage, preventing the output signal from reaching the level of the supply voltage during the rising edge of the supply voltage.
