ABSTRACT:
An integrated circuit buffer includes a source follower output transistor having an output and also connected by a voltage dropping circuit to a supply rail thereby introducing a controlled amount of Miller effect capacitance in the source follower output transistor. The buffer also has a common source output transistor and a unidirectional conducting circuit connecting between the common source output transistor and the source follower output transistor. Other buffers, palette devices, computer graphics systems and methods are also disclosed.
