Patent ID: 7411421

Claim:
A circuit for generating a differential signal, comprising: a first pair of single-ended drivers each having a respective output connected to a first line of a differential channel for transmission of electric current between the first line of the differential channel and each output of the first pair of single-ended drivers, the first pair of single-ended drivers defined to work against each other with respect to driving a first signal on the first line of the differential channel; and a second pair of single-ended drivers each having a respective output connected to a second line of the differential channel for transmission of electric current between the second line of the differential channel and each output of the second pair of single-ended drivers, the second pair of single-ended drivers defined to work against each other with respect to driving a second signal on the second line of the differential channel, wherein each of the first pair of single-ended drivers and each of the second pair of single-ended drivers is connected to receive a common input signal.
