Abstract: front page image
(EN) Provided is a signal transmission circuit having an impedance conversion circuit and a current-voltage conversion circuit. A first current is inputted to the impedance conversion circuit. The impedance conversion circuit outputs a second current that corresponds to the first current. The current-voltage conversion circuit converts the second current outputted from the impedance conversion circuit into a voltage. The impedance conversion circuit has a first current source and a current output circuit. The first current source generates a reference current. The current output circuit outputs the second current, which corresponds to a difference between or the sum of the first current and the reference current.
(FR) L'invention concerne un circuit de transmission de signal ayant un circuit de conversion d'impédance et un circuit de conversion courant-tension. Un premier courant est injecté dans le circuit de conversion d'impédance. Le circuit de conversion d'impédance délivre un second courant qui correspond au premier courant. Le circuit de conversion courant-tension convertit en tension le second courant délivré par le circuit de conversion d'impédance. Le circuit de conversion d'impédance comporte une première source de courant et un circuit de sortie de courant. La première source de courant génère un courant de référence. Le circuit de sortie de courant délivre le second courant qui correspond à une différence entre le premier courant et le courant de référence, ou à leur somme.
