Patent ID: 7855669

Claim:
A circuit device comprising: a first counter circuit responsive to a clock signal and to a first control word having a first precision to produce a first control signal related to the first control word at a first output; a second counter circuit responsive to the clock signal and to a second control word having the first precision to produce a second control signal related to the second control word at a second output; and a filtering circuit responsive to the first output and the second output, the filtering circuit adapted to produce an output signal related to the first and second control words, the output signal having a second precision that is greater than the first precision that would be obtained by filtering only the first or second output, the filtering circuit comprising: a first resistor having a first resistance coupled between the first output and the output node; and a second resistor having a second resistance coupled between the second output and the output node; wherein the first resistance and the second resistance define a ratio related to the first precision.
