1. a kind of gamma electric voltage generative circuit characterized by comprising pressure unit, partial pressure unit and compress cell;

  • The dropPress unit for the source voltage step-down by input to obtain the initial voltage of gamma electric voltage;

    The partial pressure unit is used for the galThe initial voltage of horse voltage is divided to generate each rank gamma electric voltage;

    The compress cell is described for generating auxiliary voltage signalThe auxiliary voltage signal that compress cell generates is to be added on the initial voltage of the gamma electric voltage;

    The compress cell obtains the auxiliary voltage signal by being divided the source voltage, alternatively, by describedOther circuits near gamma electric voltage generative circuit obtain the auxiliary voltage signal using time division multiplexing mode driving.
