Abstract
Methods and systems are described for monitoring and compensating an offset between a reference voltage used in a first device and a corresponding reference voltage used in a second device. The first device can include offset circuitry. The offset circuitry receives two voltage signals. The first voltage signal is equal to a first voltage value that is used as a reference voltage in the first device. The second voltage signal can be a time-varying voltage signal that has a known relationship with a second voltage value that is used as a reference voltage in the second device. The offset circuitry can then determine the second voltage value from the second voltage signal, and output an offset value based on a difference between the first voltage value and the second voltage value.
