Abstract
A DC-to-DC converter includes an error integrator that further includes a first amplifier and a second amplifier that each includes a first input for receiving a reference voltage and a second input for receiving a feedback voltage, a capacitor to an output of the second amplifier, and a resistor including a first end being coupled to an output of the first amplifier and a second end being coupled to the capacitor.
