Abstract

The present invention includes a current integrator for an organic light-emitting diode (OLED) panel. The current integrator includes an operational amplifier, which includes an output stage. The output stage, coupled to an output terminal of the current integrator, includes a first output transistor, a second output transistor, a first stack transistor and a second stack transistor. The first stack transistor is coupled between the first output transistor and the output terminal. The second stack transistor is coupled between the second output transistor and the output terminal.
