Abstract
A combined I/Q DAC is provided with a plurality of sources corresponding to a plurality of selectors in which the corresponding source drives the corresponding selector with a source signal to produce a corresponding pair of in-phase and quadrature-phase analog input signals to a summation network. Each selector routes its source signal responsive to a digital value of a corresponding in-phase and quadrature-phase bit pair.
