Current mode logic circuit

A current mode logic circuit comprising:

• a first trim resistor and a second trim resistor connected to a supply voltage;
• a first transistor connected to an input voltage;
• a second transistor connected to an inverted input voltage;
• a third transistor and a fourth transistor connected to the first transistor and the second transistor, respectively, in a cascode manner in order to control magnitudes of an output voltage and an inverted output voltage of the current mode logic circuit;
• and
• a control unit configured to control the magnitudes of the supply voltage, the input voltage and the inverted input voltage, and voltages supplied to the third transistor and the fourth transistor of the current mode logic circuit,
• wherein the third transistor is arranged between the first trim resistor and the first transistor, and the fourth transistor is arranged between the second trim resistor and the second transistor,
• wherein the control unit is further configured to control the magnitudes of the output voltage and the inverted output voltage of the current mode logic circuit by controlling the magnitudes of the voltages supplied to the third transistor and the fourth transistor, and
• wherein the control unit is further configured to individually control the voltage supplied to the third transistor and the voltage supplied to the fourth transistor in correspondence to the magnitudes of the voltages supplied to the input voltage and the inverted input voltage.
