    Settling time of current programming for AMOLED was shortened to the range of micro-second even in 10 nA of the programming current level by differentiator feedback using an active negative-capacitance circuit. The circuit can be easily implemented in a conventional CMOS current driver since neither a huge capacitance nor an additional panel circuit is required.
