| 摘要 |
The present invention relates to a signal combination circuit reducing hardware complexity and a digital-to-analog conversion circuit using the same. The signal combination circuit may comprise: a first decoding block which generates a first decoding signal group by decoding a first signal group among input signals in response to a first random number signal; a second decoding block which generates a second decoding signal group by decoding a second signal group among the input signals in response to the first random number signal; a first network block which generates a first preliminarily mixed signal group by randomly mixing the first decoding signal group in response to a second random number signal; a second network block which generates a second preliminarily mixed signal group by randomly mixing the second decoding signal group in response to the second random number signal; and a selection block which generates a mixed signal group by selectively combining the first preliminarily mixed signal group with the second preliminarily mixed signal group in response to the first random number signal. |
