CPC H03M 1/0663 (2013.01) [H03M 1/0614 (2013.01); H03M 1/447 (2013.01)] | 20 Claims |
1. A method for digital-to-analog signal conversion with distributed reconstructive filtering, the method comprising:
receiving a digital code synchronous to a clock signal having a first frequency;
determining next states of a plurality of digital-to-analog current elements based on the digital code;
combining a plurality of currents to generate an output current;
generating the plurality of currents, each current of the plurality of currents being based on a corresponding control signal of a plurality of control signals; and
generating the plurality of control signals based on the next states of the plurality of digital-to-analog current elements, each control signal of the plurality of control signals selecting a first predetermined voltage level, a second predetermined voltage level, or a transitioning voltage level for use by a corresponding digital-to-analog current element of the plurality of digital-to-analog current elements, the transitioning voltage level linearly transitioning from the first predetermined voltage level to the second predetermined voltage level over a predetermined number of periods of the clock signal.
