VOLTAGE COMPARATOR, LIQUID CRYSTAL DISPLAY DRIVER HAVING THE SAME AND TRANSITION ACCELERATION METHOD THEREOF

摘要

A voltage comparator includes an input portion, an output portion, and a diverting portion. The input portion accepts a first voltage and a second voltage and then outputs a first current based on the first voltage and outputs a second current based on the second voltage. The output portion outputs a result signal based on a difference between the first current and the second current. The diverting portion is electrically connected to the input portion and diverts a portion of the higher current amongst the first current and the second current.
