Abstract
A boost DC-DC converter includes a switching network, coupled to an inductor, controlled by a PWM driving signal. A control loop receives a voltage output and provides the PWM driving signal. The control loop generates an error signal as a function of a difference between voltage output voltage and a reference, with the PWM driving signal generated based on the error signal. A low pass filter circuit within the control loop receives the PWM driving signal and provides at least one filtered signal. An adder node of the control loop receives the at least one filtered signal from the low pass filter circuit for addition to the at least one filtered signal. The PWM driving signal is generated as a function of a sum of the filtered signal and the error signal.
