DIGITAL AMPLITUDE TRACKING CURRENT STEERING DIGITAL-TO-ANALOG CONVERTER
Abstract:
Certain aspects of the present disclosure provide a digital-to-analog converter (DAC) system. The DAC system generally includes a plurality of current steering cells, each comprising a current source coupled to at least two current steering switches, wherein control inputs of the at least two current steering switches are coupled to an input path of the DAC system. The DAC system may also include a current source toggle circuit configured to selectively disable the current source of at least one of the plurality of current steering cells, and a feedforward path coupled between the input path and at least one control input of the current source toggle circuit.
