Abstract
An apparatus of a Digital-to-Analog Converter (DAC) is provided. The apparatus includes a logic circuit for performing a logical operation based on a combination of bit values b0 through bN-1 of a digital code, and a plurality of switches for controlling an output state of a plurality of current cells based on an output of the logical operation, wherein the plurality of the current cells respectively output currents under a control of respective ones of the plurality of switches.
Claims18
An apparatus of a Digital-to-Analog Converter (DAC), the apparatus comprising:
- a plurality of current cells in the DAC,
- wherein, when a plurality of output current value candidates of a total output current value of the plurality of current cells are arranged based on a respective size of each output current value of the plurality of output current value candidates, the plurality of output current value candidates form a geometric series.
An apparatus of a Digital-to-Analog Converter (DAC), the apparatus comprising:
- a logic circuit for performing a logical operation based on a combination of bit values b0 through bN-1 of a digital code;
- and
- a plurality of switches for controlling an output state of a plurality of current cells based on an output of the logical operation,
- wherein the plurality of the current cells respectively output currents under a control of respective ones of the plurality of switches.
A method for converting a digital signal to an analog signal, the method comprising:
- performing a logical operation based on a combination of bit values b0 through bN-1 of a digital code;
- controlling an output state of a plurality of current cells based on an output of the logical operation;
- and
- outputting an analog signal by summing currents output from each of the plurality of current cells.
