Abstract
A cellular radio architecture that includes a receiver module having a delta-sigma modulator that includes a plurality of gm cells configured in stages, where each stage includes at least two gm cells and an LC filter circuit. The gm cells in each stage can be controlled to be active or inactive to convert, for example, the modulator from a fourth order modulator to a second order modulator to reduce power dissipation. Further, the gm cells can be controlled to optimize a dynamic range of the modulator and to redirect current from inactive cells to active cells in order to optimize power consumption.
