Abstract

Methods and apparatus for online common-mode voltage adjustment for a single-ended analog interface, such as in a wireless device. An example circuit for wireless communications includes a first integrated circuit and a second integrated circuit, each including different portions of a receive path. The portion of the receive path of the second integrated circuit is configured to receive, from the first integrated circuit, an analog signal including a first common-mode voltage signal, determine an estimate of the first common-mode voltage signal during an online operation of the receive path, and process the common-mode voltage signal during the online operation to generate a second common-mode voltage signal for the portion of the receive path of the second integrated circuit, based at least in part on the estimate of the first common-mode voltage signal.
