Abstract
A circuit device and method for designing a serial link receiver, which accommodates a wide input voltage range and provides tolerance to high termination voltages. The receiver is designed with a pair of RC networks connected inline between the input and the preamplifier and a common mode feedback loop, which monitors shifts in the common mode voltage and adjusts the inputs provided to the preamplifier. The circuit device maintains a flat bandwidth to accommodate all signaling rates.
