Abstract: An electronic device includes an output terminal, an output transistor having a control terminal and a conduction terminal coupled to the output terminal, and a resistor-capacitor (RC) compensation network configured to act on the control terminal of the output transistor. In addition, the electronic device includes a transconductance amplifier configured to drive the output terminal through the control terminal of the output transistor, and a Miller effect stage coupled to the RC compensation network and having an input port coupled to the transconductance amplifier and an output port coupled to the control terminal of the output transistor.
