Abstract
A differential output driver device for receiving a differential input voltage within a specific range having a first portion of a relatively higher voltage and a second portion of a relatively lower voltage and obtaining an identical voltage variation for output voltages of the first portion and the second portion is provided. The differential output driver device includes a step-down circuit for receiving the first portion of the relatively higher voltage and lowing the relatively higher voltage to a first output voltage, a step-up circuit for receiving the second potion of the relatively lower voltage and rising the relatively lower voltage to a second output voltage, a first compensation circuit electrically connected to the step-down circuit for providing a first bias to transform the first output voltage into a first compensation voltage, and a second compensation circuit electrically connected to the step-up circuit for providing a second bias to transform the second output voltage into a second compensation voltage, wherein the second compensation voltage and the first compensation voltage have the identical voltage variation value, so as to make the driver generate a periodic output voltage having a substantially regular waveform.
