The large-signal nonlinear characteristic of MOS transistors in saturation, combined with capacitances present in current mirror circuits, causes harmonic distortion. This effect is explained for a well-known current mirror circuit, and the new circuit is described which substantially reduces harmonic distortion while using only one extra standard process component. 收起
