Logic activation circuit

A logic activation circuit for switching a supply voltage line of a circuit between an on state and an off state, said logic activation circuit comprising:

• (a) a first switching device configured to controllably connect a supply voltage to the supply voltage line in a manner dependent on a changeover control signal that is applied to a control terminal of the first switching device;
• and
• (b) a second switching device configured to, in a manner dependent on a control switching pulse, connect the supply voltage line of the logic circuit to the control terminal of the first switching device for a predefined duration;
• wherein the predefined duration is approximately the duration of the control switching pulse, and the duration of the control switching pulse is longer than a charge reversal time for reversing the charge of the control terminal of the first switching device.

A method for switching at least one logic circuit on or off using a first switching device that is connected to a supply voltage line of the at least one logic circuit, the method comprising:

• a) providing charge equalization between a control terminal of the first switching device and the supply voltage line;
• and
• b) generating a changeover control signal for switching the first switching device at least in part using the charge equalization, wherein a second switching device is configured to connect the supply voltage line of the logic circuit to the control terminal of the first switching device for a predefined duration to effectuate charge equalization between the supply voltage line and the control terminal of the first switching device in order to generate the changeover control signal;
• wherein charge equalization is effected between the control terminal of the first switching device and a control terminal of the second switching device, the first switching device and the second switching device being connected to two logic circuits, the two logic circuits connected in series.
