Abstract
Embodiments are generally directed to smart impedance matching for high-speed I/O. In some embodiments, a circuit includes an impedance sensing block; a finite state machine to provide impedance tuning for a driver; and a control block, the control block to provide a feedback loop to check and tune impedance of the driver. The impedance sensing block is to sample an output voltage of the driver to determine whether the impedance of the driver is greater than or less than an impedance of the channel; and the finite state machine is to produce a signal to decrease or increase the impedance of the driver based on the determination whether the impedance of the driver is greater than or less than the impedance of the channel.
