Abstract
A first pair of single-ended drivers, each having a respective output connected to a first line of a differential channel, are defined to work against each other with respect to driving a first signal on the first line of the differential channel. A second pair of single-ended drivers, each having a respective output connected to a second line of the differential channel, are defined to work against each other with respect to driving a second signal on the second line of the differential channel. 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. A difference between the first signal on the first line of the differential channel and the second signal on the second line of the differential channel defines a differential signal that is representative of the common input signal.
