ABSTRACT:
Logic activation circuit for switching a logic circuit having at least one supply voltage line on or off, said logic activation circuit having:(a) at least one voltage supply switching device for connecting a supply voltage to a supply voltage line of the logic circuit in a manner dependent on a changeover control signal that is applied to a control terminal of the voltage supply switching device; and having(b) a charge equalization switching device which, in a manner dependent on a control switching pulse, connects the supply voltage line of the logic circuit to the control terminal of the voltage supply switching device for the duration of the control switching pulse so that charge equalization is effected between the supply voltage line and the control terminal of the voltage supply switching device in order to generate the changeover control signal.
