A common-mode shifting circuit for shifting the common-mode output voltage of a CML device to an arbitrary voltage is disclosed. A constant current source is provided at each output of the CML device. The constant current may be a positive or negative current, tending to raise or lower the common-mode output voltage, respectively. The constant current sources are preferably connected to an alternate voltage supply having a higher voltage than that the supply for the CML device. The invention further provides a method for adjusting the output signal of a current-mode logic circuit having two or more output ports, comprising the step of providing a constant current at each output port of the current-mode logic circuit, whereby the common-mode voltage at the output ports of said current-mode logic circuit is level-shifted.
