A folded cascode amplifier circuit includes: an input stage having a pair of transistors and configured to output a positive phase intermediate signal and an opposite phase intermediate signal; a cascode amplification stage having pairs of transistors connected in multiple stages, to which the positive phase intermediate signal and the opposite phase intermediate signal are supplied, and which is configured to output a positive phase output signal and an opposite phase output signal, which are differential signals; a first capacitor connected between a signal line of the positive phase intermediate signal and a signal line of the opposite phase output signal; and a second capacitor connected between a signal line of the opposite phase intermediate signal and a signal line of the positive phase output signal. |
