Abstract
A serial link receiver comprises first and second input terminals for receiving positive and negative inputs of a serial data signal, first and second broadband matching T-coils coupled to the first and second input terminals, first and second AC/DC coupling networks coupled to the first and second broadband matching T-coils, and a common mode level shifter coupled to the outputs from the first and second AC/DC coupling networks. This receiver architecture combines the ability to have a wide bandwidth input and pass through data signals at both low and high frequencies. This AC and DC coupled front end also incorporates the feature of a common mode level shifting network to place the common mode of the signal at the optimum point for the first active amplifier stage.
