  • Temperature independent reference current generation for calibration
    Patent number: 9704591
    Abstract: Disclosed herein are techniques for generating a temperature independent reference current, which may be used during calibration. The temperature independent reference current may be generated based on a current through an on-chip calibration resistor. This alleviates the need for an off chip calibration resistor, which can be costly and cause slow calibration. A voltage at one terminal of the on chip calibration resistor may be modulated to substantially cancel a temperature coefficient of the on chip calibration resistor. This may result in the current passing through the on chip calibration resistor being temperature independent. The temperature independent reference current may be based on a reference voltage and a target calibration resistance.

The temperature independent reference current may be compared with a calibration current in a ZQ calibration circuit.
