Abstract
An analog level-shifting differential amplifier for providing signal amplitude and/or common mode adjustment is disclosed. In one example, a receiver system may include a first amplification stage that is powered, for example, via an I/O power supply (e.g., VDDIO) and a second amplification stage that is powered, for example, via a core logic power supply (e.g., VDD). Arranged between the first and second amplification stages may be the analog level-shifting differential amplifier. The analog level-shifting differential amplifier may include a set of variable impedance elements for controlling the output common mode and output signal swing of the level-shifting differential amplifier.
