Worst case estimate of mismatch induced distortion in complementary CMOS current mirrors

    Research output: Contribution to journalJournal articleResearchpeer-review


    Mismatching between the MOS transistors in a current mirror causes harmonic distortion. In a complementary class AB current mirror, mismatching of threshold voltages, geometries and transconductance parameters causes a distortion which cannot be eliminated by circuit techniques but which can be reduced by careful device matching. The author presents a worst case estimate of the harmonic distortion introduced by device mismatch.
