Abstract: Electronic chips with slew-rate control at output signals are disclosed. A disclosed electronic chip includes a slew-rate control circuit and slew-rate control charging and discharging transistors wherein the transistors are coupled at an output pin of the electronic chip. According to an input signal for an output stage of the electronic chip and a signal at the output pin, the slew-rate control circuit generates the slew-rate control charging and discharging signals to separately control the slew-rate control charging and discharging transistors to charge/discharge a load capacitance at the output pin.
