Classification: G01F,H03K

Abstract:
An electronic circuit havingan input for inputting at least one information signal; an energy means for converting energy contained in the at least one information signal into a voltage supply; a control means for generating at least one switch-on control signal when an information signal arrives; and a signal processing means for storing an information item represented by the at least one information signal and/or for evaluating an information item represented by the at least one information signal and storing the secondary information obtained through the evaluation by means of at least one ferroelectric flip-flop; wherein the signal processing means can be activated by the at least one switch-on control signal for the purpose of evaluation and/or storage; and wherein, during the evaluation and/or storage, the at least one information signal may be the sole energy source for the electronic circuit; wherein the at least one switch-on control signal has the following signals; an activation signal for activating precharge transistors of the at least one ferroelectric flip-flop; transfer signal for transferring the information contained in ferroelectric capacitors of the at least one ferroelectric flip-flop onto internal data lines of the at least one ferroelectric flip-flop; and a current switching signal for switching on the voltage supply of the signal processing means.
