  • High-speed differential receiver
    Publication number: 20070008002
    Abstract: A high-speed differential receiver is used between a high voltage domain and a low voltage domain. The high-speed differential receiver includes a common mode differential amplifier coupled to a differential level shifter. The common mode differential amplifier and differential level shifter operates at the high voltage domain. The differential level shifter receives amplified differential signals from the common mode differential amplifier and provides voltage level shifted differential signals applied to a biased differential amplifier operating at the low voltage domain.
