A Direct Fast Feedback Current Driver Using an Inverting Amplifier for High-Quality AMOLED Displays
A direct fast feedback current (DFFC) driver is proposed for high-quality AMOLED displays with inverted type pixels. The driver is implemented using an integrator with a loop compensator and an inverting amplifier with a switched-capacitor gain circuit. Demultiplexing operation is realized to drive two channels using one driver. The measurement result shows settling time of 7 mu s for a panel load of 1.5 k Omega/100 pF. The driver is fabricated in a 0.35-mu m CMOS process, and the area is 120 x 131 mu m(2) per two channels.
