ABSTRACT:
A universal signal converter composed of a first current mirror having a first input terminal adapted to receive a first input signal and a first output terminal. A first common terminal is coupled to a first reference terminal. The signal converter is adapted to receive a second input signal via the first output terminal. The converter further comprises a second current mirror having a second input terminal coupled to a second reference terminal, a second output terminal adapted to supply a first output signal, and a second common terminal coupled to the first output terminal. A third current mirror has a third input terminal coupled to the second reference terminal and a third output terminal adapted to supply a second output signal. A third common terminal is coupled to the first input terminal and a bias current source is coupled between the second and the third input terminal and the second reference terminal.
