  • Patent number: 9735820
    Abstract: A LIN receiver includes a single, low power structure for both sleep and silent modes, with a single comparator for detecting LIN signaling during both sleep and silent modes as well as during active mode. In some embodiments, full receiving capability is implemented with a current as low as 5 microamps. In particular, dominant and recessive levels for the wakeup bloc are identical to those of standard LIN levels, fixed at about 3.5 V. Consequently, full LIN receiving capability is available during sleep mode.

  • Patent number: 9509321
    Abstract: A clock oscillator includes a high speed oscillator generating a high speed clock signal and comprising a digital trimming function; a counter receiving said high speed clock signal at a clock input; a time base having a low drift and controlling said counter, wherein the counter generates a difference between a reference value and a counter value; and a digital integrator receiving said difference value and providing trimming data for said high speed oscillator.

  • Patent number: 8735979
    Abstract: Mutual triggering of electrostatic discharge (ESD) fingers is improved by creating a base contact in each individual finger and connecting all of these base contacts in parallel. The local base contact in each ESD finger is located at a position where the base voltage significantly increases when the ESD current increases. Thus when an ESD finger is triggered its local base voltage will tend to significantly increase. Since all of the ESD finger bases are connected in parallel this local voltage increase will forward bias the base-emitter junctions of the other ESD fingers, thus triggering them all. By sharing the triggering current from the fastest ESD finger with the slower ones ensures that all ESD fingers are triggered during an ESD event.

  • Patent number: 7885047
    Abstract: Adaptive electrostatic discharge (ESD) protection of a device interface has very good ESD robustness when it is handled or when installed into or removed from a system. And has robust immunity to DPI, electromagnetic interference (EMI) and the like, when it is operational in a system. There is a significant capacitive coupling between the drain and gate of a ESD protection metal oxide semiconductor (MOS) device to enhance ESD protection and lower snap back voltage thereof whenever there is no (or a low level) DPI on the external connection to be protected. Whereupon when a significant DPI/EMI signal is detected on the external connection, the capacitive coupling between the drain and gate of the MOS ESD protection device is disconnected, bypassed or attenuated so that DPI/EMI immunity of the device is enhanced.
