ANALOG SIGNAL GENERATION CIRCUIT

摘要

According to the present invention, an analog signal generation circuit is provided. The analog signal generation circuit comprises: a first control section that generates a first control signal; a second control section that generates a second control signal; a plurality of current cells which are individually controlled to generate current or not to generate current based on the first and second control signals; and an analog signal output section that outputs an analog signal generated based on current generated by the current cells. The first control signal includes first and second cell state setting signals. A logical value corresponding to the first cell state setting signal is complementary to a logical value corresponding to the second cell state setting signal. Of the current cells, a current cell which is selected to be controlled by the first and the second control signal has an initialized state based on the first cell state setting signal. According to the present invention, an area occupied by a chip including the analog signal generation circuit and an amount of power consumed by the chip may be reduced.
