Abstract
A low pass filter is placed between an input pre-driver amplifier and an output driver amplifier of a display driver stage, e.g., forming a cascode amplifier. The filter suppresses noise components present in the signal from the pre-driver to prevent the noise components from being amplified and radiated by the output driver amplifier. The filter also suppresses high frequency arc currents before reaching the pre-driver amplifier.
