Claim 19:
20. An electronic system comprising a DC-DC switching power converter, the DC-DC switching power converter comprising:
a switching circuitry comprising switches, the switching circuitry configured to receive a DC input voltage and generate a DC output voltage through switching the switches;
a switching control circuitry configured to control switching of the switches with a switching signal having a switching frequency with a duty cycle, the DC output voltage generated by the switching circuitry depending on the duty cycle, wherein the switching control circuitry is configured to set the duty cycle based on a difference between the DC output voltage and a reference voltage in a closed loop configuration; and
a compensation network having a variable capacitance value, wherein the compensation network is configured to provide stability to an operation of the DC-DC switching power converter by adjusting the variable capacitance based on the switching frequency of claim 1.
