I/O interface anti-resonance passband shunting technique |
摘要 |
A method and apparatus for regulating resonance in a computer system I/O interface is provided. A shunting impedance/resistance is arranged across a power supply of the I/O interface. The shunting impedance/resistance is controlled by circuitry that is arranged to detect voltage overshoot conditions in the I/O interface. The circuitry has (1) an analog front end that is arranged to detect power supply oscillations relative to a grounded terminal, (2) an amplifier (or logic conversion circuit) that is arranged to convert an output signal from the analog front end to a digital signal, and (3) a shunting apparatus arranged to modify power supply behavior in the I/O interface dependent on the digital signal.
