发明名称 Methods and systems to calibrate push-pull drivers
摘要 Methods and systems to calibrate an on-die resistor relative to an operating voltage of an on-die push-pull driver, and to calibrate the push-pull driver relative to the on-die resistor and relative to operating voltages of the push-pull driver. The calibrated on-die resistor may be used to calibrate receive terminations, a differential transmit termination, and a simulated far-end differential receive termination. The calibrated differential transmit termination and simulated far-end differential receive termination may be coupled in parallel to calibrate current drivers. Calibration of the current drivers may include calibrating voltage swing, and may include a first phase that simultaneously adjusts compensation to the current drivers, and a second phase that individually adjusts the compensation to the current drivers.
