Method and apparatus for controlling impedance on an input-output node of an integrated circuit |
摘要 |
An input-output (I-O) buffer for an I-O node of an integrated circuit. The buffer includes a group of transistors to pull the node up. A shift register has each of two or more of its storage cells coupled to a gate of each of the transistors to control the impedance of the buffer.
