DESIGN OF GROUNDING FOR INPUT AND OUTPUT CIRCUIT

摘要

The method comprises connecting a ground line of the I/O terminal (24) and a ground line of the other buffer circuits (22) to a ground terminal (20) separately. The method includes connecting a ground line of the input terminal and a ground line of the output terminal to the ground terminal (20) separately. The method prevents the noise of ground line generated by the output terminal from being transmitted to the input terminal of the other buffer circuits to improve the speed of the semiconductor device.
