Abstract

Dispositivo di controllo di corrente particolarmente per circuiti di potenza in tecnologia MOS, il quale comprende un transistore MOS che presenta il morsetto di source collegato ad un morsetto di un carico dissipativo, il morsetto di gate collegato ad un circuito pompa, che riceve in ingresso una tensione di alimentazione ed una tensione oscillante ad onda quadra, ed il morsetto di drain collegato ad un'alimentazione. Il dispositivo comprende inoltre un amplificatore differenziale, che ha come ingressi una tensione ed una tensione di riferimento generata da un generatore di tensione di riferimento. Il dispositivo comprende un circuito di controllo, che ha come ingressi una tensione di errore generata dall'amplificatore differenziale ed una corrente di regolazione proveniente, mediante un collegamento elettrico, dal morsetto di gate del transistore MOS. Il circuito di controllo emette segnali di controllo per la regolazione della tensione di alimentazione e della tensione oscillante ad onda quadra del circuito pompa.
