Abstract
An integrated circuit (IC) includes a self-biased circuit and a start-up circuit for the self-biased circuit. The self-biased circuit generates a start-up indicator signal and an output signal. The start-up indicator signal indicates whether the self-biased circuit has started up. The start-up circuit includes a comparator, a start-up controller, and a peak controller. The comparator compares the start-up indicator signal with a reference signal generated based on supply voltages, and generates a comparison signal. The start-up controller controls a start-up of the self-biased circuit when the comparison signal is at a first logic state. Further, when the comparison signal transitions from the first logic state to a second logic state, the peak controller controls the output signal to maintain one of a voltage level and a current level of the output signal below a peak limit.
