Abstract :
A new low-distortion high-compliance CMOS current mirror is presented. 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.
