  • Patent number: 5619643
    Abstract: A circuit for generation of a reset signal in an electronic device, of the type comprising a microprocessor interlocked with a circuit generating a clock signal and memories of both the volatile type and the non-volatile type, is capable of detecting a stop in the oscillation of said clock signal and generating a logic signal coupled with the reset input of the microprocessor.
    Type: Grant
    Filed: March 31, 1995
    Date of Patent: April 8, 1997
    Assignee: SGS-Thomson Microelectronics, S.R.L.

  • Patent number: 5606531
    Abstract: An electronic device including a microprocessor, a circuit generating a clock signal, and memories of both the volatile type and the non-volatile type, incorporates a circuit for generation of a reset signal capable of detecting a stop in the oscillation of said clock signal and generating a logic signal coupled with the reset input of the microprocessor. The circuit monitors the clock signal applied to the device and, if an irregularity is detected, generate a reset signal holding the microprocessor in a safe state. The reset signal is held until the circuit generating the clock signal resumes normal operation.

  • Patent number: 5579005
    Abstract: An analog-to-digital converter (ADC), comprising an internal digital-to-analog converter (DAC), driven by a successive approximation register (SAR), and a comparator, is provided with a correction logic circuit that controls the execution of a verifying and correcting routine at the end of each conversion routine. Master-Slave cells that compose the SAR are provided with a dedicated circuitry, responding to said correction control circuit, for confirming, incrementing or decrementing the bit stored in the cell by at least an LSB. An extremely simple routine, performed at the end of each conversion cycle, allows correction of incorrectly converted digital data because of the occurrence of missing codes in the internal DAC. The corrector does not require the use of memories and/or analog circuits and is very cost- effective and permits a greatly improved production yield of complex devices containing ADCs.
