Abstract
Methods and apparatus for sharing digital-to-analog (DAC) converters in a reconfigurable DAC circuit to support two or more transmit chains of a wireless transmitter configured for different radio access technologies (RATs) and/or different transmitter architectures. One example DAC circuit generally includes at least four DACs and a plurality of switches coupled to outputs of the at least four DACs such that the DAC circuit is configured as a multi-channel DAC circuit with at least four channels for a first set of one or more frequency bands and as an interleaved DAC circuit with at least two channels for a second set of one or more frequency bands different from the first set of frequency bands.
