    Abstract

    A single-to-differential converter for generating two balanced output signals from one single-ended input signal includes first (3) and second (6) output terminals for providing the balanced output signal, a first transistor (M1) having a control electrode coupled to an input terminal (4) for receiving the input signal, a first main electrode coupled to a supply voltage terminal (1) for receiving a supply voltage and a second main electrode coupled to the first output terminal (3). A second transistor (M2) is provided having a control electrode coupled to a bias voltage terminal (5), a first main electrode coupled to the control electrode of the first transistor (M1) and a second main electrode connected to the second output terminal (6). A diode-connected third transistor (M3) is provided having its main current path coupled to the first output terminal (3), and a diode-connected fourth transistor (M4) is provided having its main current path connected to the second output terminal (6). The resulting single-to-differential converter provides low distortion and good balance at high frequencies.
