Abstract
A modulator may include a controller configured to receive in-phase (I) baseband signals and quadrature-phase (Q) baseband signals. The controller may be configured to select a section of a region defined by a number of local oscillator (LO) phases. The controller may be configured to output multiple control signals and a pair of phase selection signals. The modulator may further include multiple output stages. Each output stage may be coupled to the controller to receive a pair of the control signals, the pair of phase selection signals, and multiple offset LO signals. Each of the output stages may include a unit element.
