Dynamic impedance compensation circuit and method |
摘要 |
An impedance compensation circuit and method for an input/output buffer provides dynamic impedance compensation by using programmable impedance arrays and a dynamically adjustable on-chip load. Accordingly, among other advantages, only a single off-chip or external calibrated impedance resistor is used and only a single test pad is necessary.
