Abstract: The circuit has an input shift register (41) to receive bits flow and a comparator (42) to compare content of the register with predetermined patterns stored in a table (43). A load detector (44) detects overflow of counters with respect to a determined threshold. The detector provides the result to condition the state of a word or randomness validation bit of bit stream provided by random number generator.

Abstract: The invention relates to a memory cell with a binary value consisting of two parallel branches. Each of said branches comprises: at least one polycrystalline silicon programming resistor (Rp 1 , Rp 2 ), which is connected between a first supply terminal ( 1 ) and a point or terminal for the differential reading ( 4, 6 ) of the memory cell state; and at least one first switch (MNP 1 , MNP 2 ) which, during programming, connects one of said read terminals to a second supply terminal ( 2 ).

Abstract: The circuit for detecting the frequency of binary signals includes a circuit for detecting rising edges in the binary signals, a measuring circuit for measuring the period between the rising edges which supplies a logic state, and a shift register whose input latch stores the logic state. Also, the detecting circuit includes a shift circuit for shifting logic states of the shift register, and a decoding circuit for decoding logic states of the register, and which supplies a signal validating the signals. The detecting circuit can be used in contactless chip card readers.

Abstract: The electromagnetic transponder has an oscillating circuit to extract the high frequency amplitude modulated signal and a demodulator (17) of the digital words carried. There are separate regulators for the voltage feed and the voltage carrying the digital words (61,70). The digital word voltage has a time constant above that of the voltage feed adjustment.

Abstract: The terminal (1) uses inductive coupling to read from and write to a transponder, and includes a resonant circuit (Li,Ci) tuned to receive an AC HF excitation voltage. The resonant frequency may be altered so as to detune the LC in the event that a transponder is very close to the terminal. A capacitor (24) may be controlled by a control circuit (21) and with impedance (Li) to detect a gap of phase in relation to the signal of REF reference and to modify the capacity Ci of the capacitor (24). An Independent claim is included for a contactless system of data transmission.
