Abstract:
1. A multiplexer coupled to power and reference ground potentials and to receive unbalanced input signals, comprising: at least two inputs receiving the unbalanced input signals; at least one output; balancing means for balancing the unbalanced input signals received by said at least two inputs and producing at least first and second balanced input signals; a driver circuit clocking the inputs and applying a predetermined switching potential to the at least first and second balanced input signals under the clocking of said driver circuit; a transistor circuit having at least first and second transistors with interconnected collectors receiving the power potential, said first transistor having a base coupled via a first input signal path to said balancing means to receive the first balanced input signal and having an emitter, and said second transistor having a base coupled via a second input signal path to said balancing means to receive the second balanced input signal and having an emitter; and at least first and second outgoing signal paths from the emitter of said at least first and second transistors, respectively, combinable to form at least two output signal paths for the at least one output, the at least two output signal paths being connected symmetrically with respect to the reference-ground potential.
