Analog signal generation circuit

An analog signal generation circuit comprising:

• a first control section configured to generate a first control signal;
• a second control section configured to generate a second control signal;
• a plurality of current cells, each of the plurality of current cells configured to be controlled to generate current or to not generate current based on the first control signal and the second control signal;
• and
• an analog signal output section configured to output a first reference signal and a second reference signal that are generated based on current generated by the plurality of current cells,
• wherein the first control signal comprises a first cell state setting signal and a second cell state setting signal;
• wherein the first control section comprises a cell state setting signal generation section configured to generate the first cell state setting signal and the second cell state setting signal in response to an initialization signal;
• wherein 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;
• wherein a current cell selected to be controlled by the first control signal and the second control signal from among the plurality of current cells is configured to have an initialized state based on the first cell state setting signal;
• and
• wherein the analog signal output section comprises:
• a first output route configured to provide the first reference signal to a first output terminal;
• a second output route and a third output route configured to provide the second reference signal to a second output terminal;
• and
• a switch section configured to control connections between the second output terminal and the second output route and between the second output terminal and the third output route, based on a mode selection signal such that the second reference signal is provided to the second output terminal through one of the second output route and the third output route.
