Abstract
Disclosed herein is a layout structure of a signal driver. The layout structure of the signal driver of the present invention includes a first signal response unit, a second signal response unit, and a current source unit. The first signal response unit responds to a first input signal, and the second signal response unit responds to a second input signal. The current source unit has a plurality of bias unit pairs for restricting currents provided to the first and second signal response units to respective source currents thereof. The bias unit pairs each include at least two bias units, which are separately arranged on opposite sides of a predetermined imaginary centerline. According to the layout structure of the signal driver of the present invention, there is a benefit in that current mismatch occurring between the first and second current response units is reduced, thus consequently improving the operating characteristics of the signal driver.
