Abstract
The present invention relates to a switched mode voltage regulator circuit comprising a regulation loop coupled between the output voltage of the regulator and a switch driver. The regulation loop comprising an error signal generator supplying a digital error signal representative of a voltage difference between the output voltage and a reference voltage. The regulation loop further comprises a linear digital filter and a non-linear digital filter both coupled for receipt of the digital error signal and a digital summer coupled for receipt of linearly and non-linearly filtered digital error signals to provide a combined digital error signal. A digital pulse modulator is configured to generate the pulse width or pulse density modulated driver control signal in accordance with the combined digital error signal.
