the desired level shift to shift the common mode voltage of the incoming signal to the level tolerable by low voltage high speed transistors in the receiving integrated circuit application_number US 64875609 A description in broad concept the subject system and method provide a voltage level shifting circuit interface to preserve operational compatibility between transmitting and receiving integrated circuits a system realized in accordance with one exemplary embodiment of the present invention employs a switched capacitor technique to translate the dc voltage level of an incoming signal in a controlled manner to a desired level in the particular example of serial transmission of a signal through differentially paired lines the system operates to level shift an incoming differential signal 39 s common mode voltage to a desired level and does so without appreciable attenuation of the signal u201c riding u201d on the incoming common mode voltage or any reduction in the prevailing signal bandwidth in an exemplary embodiment the system provides a serial interface for high speed differential data transfer between transmitting and receiving integrated circuits which may not otherwise be compatible in the common mode voltage levels they may safely support the system provides the required shift of common mode voltage to a level safe for the receiving circuit the shifted level is preferably defined by the outputs of a differential offset correction unit for the receiving.
