Abstract
Disclosed is a source follower with Vgs compensation, such that the output voltage precisely follows the input voltage by various arrangements of MOSFET's, switches, and capacitors. In addition, such a source follower that the output voltage precisely follows the input voltage can be implemented without adding too many components. The source follower disclosed in the present invention can be used in the driver circuit for a liquid crystal display (LCD).
