  • Patent number: 11990902
    Abstract: A repeater for open-drain bus communication and a system including the same is provided. The repeater includes at least one repeating unit having an A-side terminal connected to an A-side open-drain bus, and a B-side terminal electrically connected to a B-side open-drain bus. The repeater has a first mode to receive a signal at the A-side and to produce a signal at the B-side. The repeating unit includes a B-side accelerator element connected to the B-side terminal. The repeating unit when in a first mode includes a first control unit to, control the B-side accelerator element to pull up a voltage at the B-side when the voltage at the A-side surpasses a first threshold voltage during a rising edge of the voltage, and to subsequently control the B-side accelerator element to stop pulling up the voltage at the B-side when the voltage at the B-side surpasses a second threshold voltage.

  • Publication number: 20230408556
    Abstract: A system for sensing a current through a transistor is provided and a DC-DC converter including one or more such systems. The system includes a transistor module, including: a primary transistor electrically connected between a first and a second terminal; and a secondary transistor electrically connected between the first and a third terminal, a control terminal of the secondary transistor is electrically connected to a control terminal of the primary transistor. The system includes a current sensing module electrically connected to the transistor module and having an output terminal. The system is operable in a first mode in which the current sensing module outputs, at the output terminal, a first output signal indicative of a current through the primary transistor in a first current direction based on a voltage difference between the third and the second terminal, the first current direction being from the first to the second terminal.

  • Publication number: 20230097034
    Abstract: The present disclosure relates to a bi-directional bus repeater. The present disclosure further relates to a communication bus including a bi-directional bus repeater, and to a communication system including the communication bus. The bi-directional bus repeater includes a first input terminal, a second input terminal, a first pulldown element connected to the first input terminal, and a second pulldown element connected to the second input terminal. By ensuring that the activation of the first and second pulldown elements is dependent on the state of the corresponding input terminal and the detection of a high-to-low transition of the corresponding other input terminal, the problem of self-locking can be avoided or at least minimized.

  • Publication number: 20220382700
    Abstract: A repeater for open-drain bus communication and a system including the same is provided. The bus repeater includes an A-to-B buffer to receive the signal at the A-side terminal and to produce a first buffered signal, a B-side pull-down control unit to produce a first control signal based on the received first buffered signal, and a B-side pull-down element to pull down the voltage at the B-side terminal based on the first control signal. The B-side pull-down element includes a B-side pull-down transistor that is arranged in between the B-side terminal and a B-side ground reference terminal. The first control signal controls a voltage at the control terminal of the B-side pull-down transistor. The B-side pull-down control unit includes a B-side comparing unit to compare the voltage at the B-side terminal to a first reference voltage, and to generate the first control signal based on a result of the comparison.

  • Patent number: 7196541
    Abstract: An electronic circuit has a programmable logic cell with a plurality of programmable logic units that are capable of being configured to operate in a multi-bit operand mode and a random logic mode. The programmable logic units are coupled in parallel between an input circuit and an output circuit. The input circuit can be configured to supply logic input signals from the same combination of the logic inputs to the programmable logic units in the random logic mode. In the multi-bit operand processing mode the input circuit is configured to supply logic input signals from different ones of the logic inputs to the programmable logic units. The programmable logic units are coupled to successive positions along a carry chain at least in the multi-bit operand mode, so as to process carry signals from the carry chain.
