    Abstract: A system and method are provided for reducing the current consumption of receivers such as direct conversion receivers associated with modem receiver systems as well as low IF receiver systems, among others. The system and method dramatically reduce the current consumption in receivers due to three factors. 1) Since the filter 302 also performs the VGA function, the current consumption of the VGA 304 is eliminated; 2) Since the gain partitioning of the structure 200 depicted in FIG. 2 is superior, the noise performance of the filter 302 is greatly reduced; and the base band LNA 304 can be eliminated, also eliminating the current consumption of the base band LNA 304; and 3) The folded gm structure 500 depicted in FIG. 5 can be used, cutting the current consumption of the base band filter 302 by a factor of two. The structure 200 notably does require control circuitry to set the gm values of the forward and feedback paths independently.
