Digital-to-analog conversion circuit and receiver including the same

A digital-to-analog conversion circuit comprising:

• a first digital-to-analog converter (DAC) comprising:
• a first binary-to-thermometer code converter (BTC) configured to convert a first digital code received through a first input terminal to a first thermometer code;
• a plurality of first current cells connected between a first voltage source and a first output node, and configured to provide a first current to the first output node based on the first thermometer code;
• and
• a first current-to-voltage converter directly connected between the first output node and a second voltage source;
• and
• a second DAC comprising:
• a second BTC configured to convert a second digital code received through a second input terminal to a second thermometer code;
• a plurality of second current cells connected between the first voltage source and the first output node in parallel with the plurality of first current cells, and configured to provide a second current to the first output node based on the second thermometer code;
• and
• a second current-to-voltage converter directly connected between the first output node and the second voltage source in parallel with the first current-to-voltage converter,
• wherein the first current-to-voltage converter and the second current-to-voltage converter are configured to convert a sum of the first current and the second current to a first analog voltage corresponding to a weighted sum of the first digital code and the second digital code, and output the first analog voltage at the first output node.
