A voltage adder includes a first amplifier, a feedback resistor, and a control current source. The first amplifier includes a first input terminal to which a first voltage is input, a second input terminal connected to a feedback node, and an output terminal connected to an output node. The feedback resistor is connected between the output node and the feedback node. The control current source allows an addition current corresponding to a second voltage to flow through the feedback resistor.
