Wide range input voltage differential receiver
A method and apparatus for receiving reduced voltage swing signals is disclosed. A first amplifier may generate a first intermediate signal based on a difference between voltage levels of a first and second input signals, and a second amplifier may generate a second intermediate signal based on a difference in the voltage levels between the second and first input signals. A regenerative amplifier may increase a difference in the voltage level of the first and second intermediate signals using regenerative feedback and the voltage levels of the first and second input signals. A latch circuit may generate first and second output signals using the first and second intermediate signals.
