Abstract
A current-steering type digital-to-analog converter (DAC) is disclosed. The DAC includes a first sub-DAC, a second sub-DAC and a controlling device. Both the first sub-DAC and the second sub-DAC are configured to receive input signals. The controlling device selectively and periodically sends output signals of either the first sub-DAC or the second sub-DAC to a resistive load while sending output signals of the remaining one of the two sub-DACs to a dummy resistive load. An output of the DAC is provided at the resistive load.
Claims19
A digital-to-analog converter (DAC) comprising:
- a first sub-DAC for receiving a first input signal from an input;
- and
- a second sub-DAC for receiving a second input signal from said input, wherein said second input signal is different from said first input signal, wherein one of said first or second sub-DAC selectively and periodically sends a first output signal to a load while the remaining one of said sub-DACs sends a second output signal to a dummy load, wherein an output of said DAC is provided at said load.
A method for setting internal bias points of a digital-to-analog converter (DAC), said method comprising:
- receiving a first input signal by a first sub-DAC from an input;
- receiving a second input signal by a second sub-DAC from said input, wherein said first input signal is different from said second input signal;
- and
- selectively and periodically sending an output signal of said first or second sub-DAC to a load while sending an output signal of the remaining one of said sub-DACs to a dummy load, wherein an output of said DAC is provided at said load.
