Abstract:
Methods and systems are provided for dynamic power switching in current-steering digital-to-analog converters (DACs). A DAC circuit may be configured to apply digital-to-analog conversions based on current steering, and to particularly incorporate use of dynamic power switching during conversions. The DAC circuit may comprise a main section, which may connect a main supply voltage to a main current source. The main section may comprise a positive-side branch and a negative-side branch, which may be configured to steer positive-side and negative-side currents, such as in a differential manner, to effectuate the conversions. The dynamic power switching may be applied, for example, via a secondary section connecting a main current source in the DAC circuit to a secondary supply voltage. The secondary supply voltage may be configured such that it may be less than the main supply voltage used in driving the current steering in the DAC circuit.

Claim (Index 21):
A system comprising:\n a digital-to-analog converter (DAC) operable to receive an input digital code comprising a plurality of bits, wherein the DAC comprises a plurality of cells, each cell of the DAC comprising a current source and at least one primary switch, wherein the at least one primary switch is operable to steer a current from the current source according to a bit of the input digital code; a secondary source; and one or more secondary switches operably coupled to a first cell of the plurality of cells, wherein the system is operable to steer the current in the first cell to the secondary source.
