WIDEBAND CLASS AB CRT CATHODE DRIVER

摘要

A cathode driver of wide-band AB grade CRT(cathode ray tube) is provided. The wide-band driver comprises: an output terminal for providing an output signal as function of input signals; an excess pull-up circuit for providing an excess pull-up signal to the output terminal; and an excess pull-down circuit for providing an excess pull-down signal to the output terminal, wherein both of the excess pull-up and the excess pull-down circuits are operated as a cascade or a current miller.
