Bias compensation method and system for minimizing process, voltage and temperature corner variations |
摘要 |
A system and method for calibrating bias in a data transmission system including a calibrated bias having impedance calibration for accommodating parameter variations in the data transmission system. A current mirror receives and balances bias currents between the calibrated bias and an output driver from the data transmission system. A digital compensation logic circuit is connected to the calibrated bias to adjust the calibrated bias for variations in parameters causing a current tail effect. A calibration logic circuit adjusts calibration due to variations in operational parameters, such that the tail current variations are minimized. |
