  • Patent number: 8692583
    Abstract: An apparatus, system, and method are provided for a differential integrated input circuit. The apparatus includes n-type semiconductor devices and p-type semiconductor devices. The p-type semiconductor devices are cross-coupled with the n-type semiconductor devices. Each of the p-type semiconductor devices biases a corresponding n-type semiconductor device.
    Type: Grant

  • Publication number: 20070159154
    Abstract: The invention relates to a voltage regulator circuit arrangement comprising a voltage regulator for generating an out-put voltage in dependence of a reference signal, characterized in that a reference signal generation circuit is provided for generating said reference signal comprising a plurality of inputs connected to internal terminals, whereby a sub-set of said plurality internal terminals is connected to an external terminal.

  • Publication number: 20050246555
    Abstract: An integrated circuit has an input connection for connecting an external signal conductor that passes signals to execute functions in the device. The external signal conductor can pick up strong interfering signals with high frequency content, for example when the device is used in a car. To protect against unintended execution of functions the device contains a timer circuit comprising a capacitance and a current supplying circuit coupled to an integration node. A discharge diode is coupled between the input connection and the integration node, with a polarity such that the discharge diode, when in forward bias, is capable of draining current from the current supplying circuit. A detector is coupled to the integration node for generating a signal to be supplied to the integrated circuit device to respond to a signal transition on the conductor. The diode serves to reset integration on the integration node before the detector detects the transition in case of short pulses.

  • Publication number: 20050025084
    Abstract: The communication bus system comprises a plurality of node circuits (10a-d) and a relay circuit (12, 14, 16) coupling the node circuits (10a-d). The relay circuit (12, 14, 16) has a transceiver circuit (124, 164) for relaying messages (21) between the node circuits (10a-d) in a normal mode. The transceiver circuit (124, 164) is powered down in a sleep mode. A detector circuit (120, 160) detects an incoming message (41) when the relay circuit (12, 14, 16) is in a sleep mode. A mode control circuit (122, 162) powers up the transceiver (124, 164) in response to detection of an incoming message (21). Steps are taken that ensure, in the normal mode, that messages (21) will not be relayed in unreadable form. The mode control circuit (122, 162) is arranged to cause the transceiver (124, 164) to relay a remainder (25) of the incoming message (21) after power up.
