  • Reducing noise associated with local reference-potential fluctuations in mixed-signal integrated circuits
    Patent number: 7391348
    Abstract: An integrated circuit (IC) adapted to (i) measure a voltage differential between a ground potential external to the IC and a ground potential internal to the IC and (ii) based on the measurement result(s), adjust a signal referenced to the internal ground potential to reduce signal error associated with the voltage differential. In one embodiment, the IC is adapted to monitor the voltage differential in real time and use the presently measured voltage differential to perform signal adjustment. In another embodiment, the IC has a plurality of registers, each register adapted to store a voltage-differential value corresponding to a particular configuration of the IC, which values are written into the registers during an initialization procedure. During normal operation, the IC controllably selects from the stored values one corresponding to the current IC configuration.
