Preferred embodiments of the present invention are a switching converter, an integrated circuit package, and method for controlling a switching converter. An embodiment of the invention is a switching converter comprising a first compensation network having a first node coupled to an error voltage and a second node coupled to electrical ground and a second compensation network having an input coupled to the error voltage. A frequency domain transfer function of the first compensation network comprises a first zero and a plurality of first poles, and a frequency domain transfer function of the second compensation network comprises a second zero and a second pole.

Switching converter and method to control a switching converter

In a low-gain current-mode voltage regulator having a PWM comparator in response to the varying output voltage and inductor current of the voltage regulator to produce a PWM signal to regulate the output voltage, an offset signal is derived from a subtraction between the inputs of the PWM comparator, and the offset signal is injected into the PWM comparator to cancel the output offset of the voltage regulator.

An adding circuit includes storage capacitors and a a switch mechanism, the storage capacitors being charged up via voltage signals to be added during a first clock phase. During a second clock phase, the storage capacitors are connected in parallel, with the result that a charge equalization occurs. After the charge equalization, the voltage dropped across the parallel-connected storage capacitors is equal to a sum of the signals to be added except for a scaling factor. In one embodiment, the adding circuit is used in a sigma-delta modulator circuit.
