Various embodiments of the invention increase current monitoring accuracy in switching converters. In particular, certain embodiments of the invention allow reduce noise associated with transients that are typically generated at transitions when power FETs are turn on and off and allow to accurately sense inductor DC current of switching converters, thereby, increase current monitoring accuracy without requiring any blanking circuitry. In certain embodiments of the invention, this is accomplished by an acquisition circuit that dynamically monitors current in various operating modes. A phase frequency detector (PFD) and control circuit in the acquisition circuit automatically align a narrow sampling window and the midpoint of a turn-on signal. Certain embodiments utilize an analog multiplier circuit to sense current in skip mode operation.
