Abstract
Un primo e un secondo transistore bipolare collegati a diodo hanno rispettivi terminali collegati a massa e rispettivi terminali opposti pilotati da rispettivi generatori di correnti costanti e diverse fra loro. I due transistori pilotano mezzi integratori-sommatori comprendenti:a) un primo condensatore collegato fra un nodo comune e un primo commutatore atto a collegarsi alternatamente ai terminali opposti dei due transistori;b) un secondo condensatore collegato fra detto nodo comune e un secondo commutatore atto a collegarsi alternatamente al terminale opposto del secondo transistore e la massa;c) un amplificatore;d) un primo interruttore collegato fra l'uscita e l'ingresso di detto amplificatore.Secondo l'invenzione, un secondo interruttore è collegato fra detto primo nodo comune e l'ingresso di detto primo amplificatore.(Rif. Fig. 2).
