Video line drivers that operate using a single external supply voltage,
without the need for large external capacitors (e.g., 470 uF) on the
output, are provided. In accordance with an embodiment, a video line
driver includes a charge pump and a plurality of amplifiers. The charge
pump uses the single external supply voltage to produce a further voltage
having an opposite polarity than the external supply voltage. The
plurality of amplifiers are each powered by the external supply voltage
and the further voltage produced by the charge pump. Each amplifier
receives a portion of a video signal and outputs an amplified version of
the received portion of the video signal. The video signal can include,
e.g., an R portion, a G portion and a B portion, or a Y portion, a Pb
portion and a Pr portion. This abstract is not intended to be a complete
description of the invention.
