Abstract
A method for operating a radio frequency digital to analog conversion circuitry with a number of cells if a first input sample and a subsequent second input sample have different signs, comprises generating a first analog signal corresponding to the first input sample using a first subset of the number of cells of the digital to analog conversion circuitry with a local oscillator signal having a first polarity. The method further comprises applying a second local oscillator signal with an inverted polarity to a second subset of cells of the digital to analog conversion circuitry when a number of cells from the first subset of cells are used and selecting a number of cells from the second subset of cells to generate a second analog signal corresponding to the second input sample.
