Abstract
A digital-to-analog converter includes a sampling resistor network circuit, an operational amplifier, a feedback resistor, and a compensation current generation circuit. The sampling resistor network circuit controls a sampling resistance value of the sampling resistor network circuit based on a sampling codeword, and generates an output current based on a voltage difference between a first reference voltage and a voltage at a first input terminal of the operational amplifier as well as the sampling resistance value. The compensation current generation circuit generates a compensation current based on the sampling codeword. The compensation current is used to compensate for an offset current generated by an offset voltage in the sampling resistor network circuit in order to make a sum of the compensation current and the offset current equal to a first constant. The first constant is independent of the sampling codeword.
