Abstract:
A single-ended receiver includes an internal voltage generation circuit to set a first internal reference voltage (Vref). A model voltage generation circuit is configurable to receive an external reference voltage to be calibrated during an initial calibration. The model voltage generation circuit is configurable to track an offset value for voltage-temperature (VT) drift and the offset value is applied to the internal voltage generation circuit to calibrate the internal Vref during a periodic calibration of the single-ended receiver.
