In particular, calibration circuits and methods are provided to enable accurate impedance matching at a reference voltage Vref of K*Vddq, where K is a number between 0 and 1. In some embodiments, a calibration circuit for impedance matching at a reference voltage of K*Vddq uses a ratioed current mirror. In another embodiment, a calibration circuit for impedance matching at a reference voltage of K*Vddq uses a ratioed mirror pull-up circuit. In yet another embodiment, a calibration circuit for impedance matching at a reference voltage of K*Vddq uses a ratioed target impedance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration circuit for on-chip drive and on-die termination","description":"Calibration circuits and methods to set an on-chip impedance to match a target impedance where the reference voltage does not equal one-half of the positive power supply voltage Vddq are described.
