Abstract
An error amplifier circuit includes: a plurality of error amplifiers, each of which obtains an output for an error between two input signals; and a multiplexer, which selects or deselects the outputs of the plurality of error amplifiers and outputs the selected output of the error amplifier as a control signal for a circuit to be controlled. Regarding the multiplexer, in an error amplifier which is one of the plurality of error amplifiers and of which the output is not selected, a delay element arranged in an input path of the one error amplifier is short-circuited to widen the bandwidth of the error amplifier.
