Abstract
The common-mode input voltage of a common-gate input amplifier receiving a differential signal is set in an open-loop manner by basing the bias current and/or source load impedances of the common-gate amplifier on a transmitter bias current and driving impedance. The common-mode input voltage of a common-gate input amplifier receiving a differential signal may be set in a closed-loop manner using a feedback loop having a captured target voltage compared to the common-mode input voltage at a node of the amplifier. The common-mode input voltage of a common-gate input amplifier receiving a differential signal may be set in a continuous time closed loop manner by sending a reference current through resistances that are multiples of a resistance used to generate the reference current.
