Abstract
A signal transmission circuit includes a driver circuit that includes complementary inverters, each of the complementary inverters including a plurality of transistor switches, each of the plurality of transistor switches including a pair of transistors, one of the pair of transistors operating in a saturation region and another of the pair of transistors operating in a triode region to cause a certain impedance, and that drives each of the plurality of transistor switches in accordance with complementary signals so as to output complementary voltages to a transmission line; and first voltage sources that supply operating voltages to the driver circuit so as to adjust amplitudes of the complementary voltages output from the driver circuit to the transmission line.
