Abstract
Receiver circuitry for an input/output device includes first stage circuitry and second stage. The first stage circuitry has a first input to receive an input signal, voltage adjustment circuitry, and differential amplifier circuitry. The first stage circuitry is coupled to the first input and has a transistor pair to receive the input signal, and adjust a voltage value of the input signal to generate an adjusted signal. The differential amplifier circuitry receives the adjusted signal and a reference signal, and generates a first differential signal and a second differential signal. The second stage circuitry receives the first differential signal and the second differential signal, and generates an output signal based on the first differential signal and the second differential signal.
