Abstract: The invention relates to a method for evaluating the effects of a multiconductor interconnection on electrical variables in an electronic circuit or system, which takes into account the frequency dependent couplings between the conductors to obtain an accurate evaluation of effects such as propagation delay, attenuation, linear distortions, echo and crosstalk. The method comprises the steps of: identifying segments having suitable properties; defining, for each segment, a per-unit-length external impedance matrix of the segment and a per-unit-length internal impedance matrix of the segment; defining, for each segment, a model of the per-unit-length internal impedance matrix of the segment; and simulating the circuit using, for each segment, a multiconductor transmission line model and the model of the per-unit-length internal impedance matrix of the segment defined at the previous step.

Abstract: The invention relates to a current-sensing differential amplifier having a balanced input. A balanced-input current-sensing differential amplifier of the invention has a first signal input terminal, a second signal input terminal, a first signal output terminal and a second signal output terminal. The balanced-input current-sensing differential amplifier comprises a first current mirror, the input terminal of the first current mirror being coupled to the first signal input terminal, a second current mirror, the input terminal of the second current mirror being coupled to the second signal input terminal, a third current mirror, one of the output terminals of the third current mirror being coupled to the common terminal of the first current mirror and to the common terminal of the second current mirror, three current sources and an output circuit.
