Digital differential signal transmitter for low supply voltage

摘要

A digital differential signal transmitter circuit for a low supply voltage. A phase correction circuit for correcting digital signals transmitted through two signal paths in such a way as to have a phase relationship of differential signals and duty cycle correction circuits for correcting the digital signals in such a way as to maintain signal integrity in spite of changes in process, supply voltage and temperature are installed on the two signal paths so that the distortion of digital differential signals is compensated for. Power consumption at a final output section of the transmitter circuit is reduced. Impedances of the transmitter circuit and transmission lines are matched so that the transmitter circuit can operate insensitively with respect to operation circumstances.
