Definitions
- the invention relates to an energy supply device or a circuit arrangement with this energy supply device.
- the object of the invention is to provide an energy supply device, or a circuit arrangement with a data processing device, in which it is not possible to draw conclusions about processes or data in the data processing device from the monitoring of the energy consumption.
- the specified measures also serve to suppress an instantaneous value of the energy consumption on
- Fig.l a first exemplary embodiment according to the invention
- Fig.2 shows a further development of that shown in Fig.l.
- FIG. 3 shows a further embodiment of the exemplary embodiment according to the invention shown in FIG. 1 and FIG. 2 shows a second exemplary embodiment.
- Fig.l shows a first exemplary embodiment according to the invention. This shows that a voltage U is present at an input E, which voltage is supplied to a switch S when this switch S assumes a first switching state ZI. Furthermore, the voltage is supplied to a capacitor CZ in this switching state. The capacitor CZ is charged to the value of the voltage U present at the input E. He takes
- the data processing device 1 in turn is to be operated at a clock rate T. If the switchover frequency used to charge the capacitor C again and again is less than twice the clock rate T, the current with which the data processing device 1 can be inferred cannot be inferred from the charging current which charges the capacitor CZ is operated from the capacitor C.
- sampling filter now makes it possible to deliberately violate the sampling theorem with a switching frequency (sampling frequency) that is below twice the switching frequency of the circuit and thus to make the reconstruction of the original current curve considerably more difficult.
- sampling frequency sampling frequency
- the reconstruction can be made more difficult by the temporal variation of the switching frequency.
- capacitors ZI to ZN are provided, which are charged with the voltage U from the voltage input via respective switches S1 to SN. It is now provided that either the capacitors are charged simultaneously with the input voltage U in order to be subsequently connected in parallel to the capacitor C. This reduces the voltage ripple across capacitor C without transmitting more information to input E. Another possibility is to continuously connect the capacitors CZ1 to CZN in a more complex order to the input E and to the capacitor C. In both cases, the charging current obtained from the input voltage is equalized or smoothed. Furthermore, it can be provided in both cases that the arrangement described is operated as a voltage regulator for the data processing device 1. In this case, the changeover rate T is regulated as a function of the current consumption, that is to say of the supply voltage UV.
- FIG. 1 A further development of the exemplary embodiment shown in FIG. 1 is shown in FIG.
- the switch S has a third state Z3.
- a parallel voltage regulator 2 is provided in parallel with the capacitor C and the data processing device 1.
- the difference in operation as shown in Fig. 3, to the arrangement shown in Fig.l, lies in the fact that after reloading the charge stored on the capacitor CZ to the capacitor C, the switch S assumes the state Z3. In this position, the capacitor is connected in parallel to a discharge circuit 3. This discharge circuit 3 now discharges the capacitor CZ to a predetermined value. Then the switch S switches back to the state ZI, so that the capacitor CZ is connected to the input E, so that it is recharged by the input voltage U.
- the capacitor has CZ the new charging to a predetermined state, so that it is always charged with the same charging current from the input voltage U.
- All three configurations of the first exemplary embodiment according to the invention are suitable for being designed as an integrated circuit on a semiconductor chip.
- an input voltage of 3 volts is required at a switching frequency of 1 MHz, and a capacitance of 1 nF is required for the capacitor CZ.
- a current of 1 mA is transmitted.
- the switch S is formed by a conventional electronic switch.
- the circuit arrangement is preferred for integrated circuits which are produced using a technology using ferroelectric dielectric.
- the dielectric constant E can be used, increased compared to the previously used dielectric constant, so that in such a case a smaller area is required for a given capacitance.
- FIG. 4 shows a second embodiment.
- the capacitance CZ according to FIGS. 1 to 3 is replaced by an inductor.
- switch S With switch S, the following effects are achieved by switching from state ZI to state Z2.
- a current I (T) is impressed into the inductance L, so that a magnetic field is formed.
- This magnetic field corresponds to a magnetic energy stored by this coil.
- the switch S changes from the state ZI to the state Z2, the coil is in turn connected to the capacitor C, which is again charged to a voltage UV (T) by a charging current from the magnetic energy stored in the inductor L.
- a so-called free-wheeling diode D In order to prevent the occurrence of overvoltages when switching from the state ZI to the state Z2, a so-called free-wheeling diode D must be provided in parallel with the inductance L. Should it not be possible to add inductance L to the half integrating the conductor chip, it can be arranged at least directly on the surface of the semiconductor chip.
- the developments according to FIG. 2 and FIG. 3 can be correspondingly transferred to this second exemplary embodiment.
