Method and system for reducing I/O noise and power |
摘要 |
In an I/O circuit, noise reduction and power savings are achieved by providing feedback from the output of the I/O driver to control the current through the pre-driver and thereby the current through the driver transistors after a non-zero time delay following a low to high or high to low data signal change.
