Abstract

A power-efficient fully differential AB Miller op-amp with accurate control of the output quiescent current is introduced. It can drive a wide range of resistive (200Ω-1MΩ) and capacitive loads (5pF-300pF). It has large dynamic and static current efficiencies of 8.6 and 7.9 and small-signal figures of merit higher than 7.4 for (1MΩ-200Ω) resistive load.
