摘要： An LVDS output circuit steadily supplying an output current of magnitude I includes a current source 101 outputting a current of 2I, current sources 102, 103, 106, 107 allowing a current of ΔI to flow therethrough, and current sources 104, 105 allowing a current of I−ΔI to flow therethrough. Switches 117, 118 switch the polarity of the output depending on an input signal 116. At the time of polarity transition, switches 108, 109 are OFF while switches 110, 111 are ON. The output amplitude is thus (I+ΔI). Alternatively, the switches 108, 109 are ON while the switches 110, 111 are OFF. The output amplitude is thus (−I−ΔI). That is, although the balance of currents flowing through the current sources 102 to 107 changes permitting preemphasis, the total of the currents flowing through the current sources 102 to 107, i.e., power consumption is kept constant. This speeds up signal transmission and minimizes power supply noise.
