    Abstract: A device for the regeneration of a clock signal from an external serial bus includes a ring oscillator and counter. The ring oscillator provides n phases of a clock signal. Of these n phases, one phase is used as a reference and is applied to the counter. It is thus possible to count the number of entire reference clock signal periods between a first pulse and a second pulse received from the bus. In reading the state of the phases in the oscillator upon reception of the second pulse, a determination is made for a current phase corresponding to the phase delay between the reference clock signal and the second pulse of the bus. By using a regeneration device that also includes a ring oscillator and a counter, it is possible to regenerate the clock signal of the bus with high precision.

    Abstract: Random signal generator comprises an MOS transistor as an electronic noise source. The MOS transistor is operated with a drain source current having a random component and has means for producing a binary random signal from the random drain source current. The current channel is arranged to be curved or S shaped by suitable doping. The invention also relates to an integrated circuit with a binary signal generator based on an MOS transistor. The circuit has suitable connections for connecting to other circuits. An Independent claim is made for a method for generating a random signal from an electronic noise source, in which an MOS transistor with an S or screw shaped channel is used.

    Abstract: The device includes a control circuit (CC) with n primary circuits (CE1,CEn), each representing a critical; path of an electronic circuit to be monitored. Each primary circuit delivers a control signal (POR1,.. PORn) which is then transmitted to a logical gate OR. A common signal (POR) is generated by the gate. A voltage detector (DET) delivers a temperature independent signal (TPOR) to the other input of the logical gate. The signal TPOR has an amplitude equal to the threshold voltage (Vs) of the device.
