A high-speed high-linearity time-interleaved dynamic operational amplifier circuit includes a first current channel and a second current channel. The first current channel includes a first MOS transistor, a second MOS transistor and a third MOS transistor which are sequentially connected in series between a high level and a ground level. The first MOS transistor and the second MOS transistor have opposite conductivity types. A control end of the first MOS transistor is connected to a control end of the second MOS transistor. The second current channel includes a fourth MOS transistor, a fifth MOS transistor and a sixth MOS transistor which are sequentially connected in series between the high level and the ground level. The fourth MOS transistor and the fifth MOS transistor have opposite conductivity types. A control end of the fourth MOS transistor is connected to a control end of the fifth MOS transistor.
