1. A DC-DC converter for converting an input DC voltage to an output DC voltage, comprising:

  • a first switch coupled to said input voltage and operable for generating said output DC voltage at an output node;

    a capacitor coupled to said output node and operable for determining a zero frequency of said DC-DC converter;

    a first resistor for coupling said capacitor to ground; and

    a voltage divider coupled to said capacitor in parallel and coupled to said first resistor in series and operable for determining said zero frequency.
