  • Gated thyristor and related system and method
    Patent number: 7619863
    Abstract: An embodiment of a protection circuit, comprising a first PNP-type bipolar transistor and a second NPN-type bipolar transistor, the base of the first transistor being connected to the collector of the second transistor and the collector of the first transistor being connected to the base of the second transistor, in which a MOS transistor is connected between the collector and the emitter of the second transistor.
    Type: Grant

  • Electrostatic discharge protection device comprising several thyristors
    Patent number: 7113377
    Abstract: An electrostatic discharge protection device comprises several thyristors which are connected in parallel between two nodes of an electrical circuit. It also includes a control circuit having an output connected to the control trigger terminal input of each of the thyristors. In response to an abnormal variation in a voltage between the two nodes being detected, the control circuit initiates a triggering current on the output so as to trigger the thyristors to conduct current between the two nodes. Preferably, the thyristors are arranged in a semiconductor substrate so as to have low hold voltages and small geometrical dimensions.

  • Method and device for integrated testing for an analog-to-digital converter
    Patent number: 6642870
    Abstract: A device for self-testing of an analog-to-digital converter includes elements for applying to the converter test signals and analyzing elements. The analyzing elements include common resources (10,36) integrated in the circuit bearing the converter and capable of being configured to determine successively shift, gain and non-linearities of the converter and elements for configuring and controlling the common resources (10,36) so as to adapt them to the characteristics to be determined.
