ABSTRACT:
An apparatus and method for generating differential signals. The apparatus includes a first operational amplifier receiving a first signal, a second operational amplifier receiving a second signal, and a first transistor. The first transistor includes a first gate, a first terminal, and a second terminal. Additionally, the apparatus includes a second transistor. The second transistor includes a second gate, a third terminal, and a fourth terminal. Moreover, the apparatus includes a first resistor coupled to the first terminal and the third terminal, and a second resistor coupled to the second terminal and the fourth terminal. Also, the apparatus includes a first current supplier coupled to the first terminal, a second current supplier coupled to the second terminal, a third current supplier coupled to the third terminal, and a fourth current supplier coupled to the fourth terminal.
