  • Publication number: 20240085469
    Abstract: A transmitting and receiving circuit may include a first CMOS inverter configured to receive a first power supply signal and a first input signal. The transmitting and receiving circuit may include a first calculation amplifier including a non-inverted input terminal connected to an output terminal of the first CMOS inverter, and a first resistor connected between the output terminal of the first calculation amplifier and a first node. The output terminal of the first calculation amplifier and an inverted input terminal of the first calculation amplifier may be connected to each other. A first output signal may have a level smaller than that of the first input signal and may be output to the first node.

  • Patent number: 10855497
    Abstract: A semiconductor device including a signal generator and decoding and timing skew adjusting circuit is provided. The signal generator is configured to receive n multi-level signals having m signal levels and convert the n multi-level signals into n*(m?1) single level signals having two signal levels. The decoding and timing skew adjusting circuit is configured to receive the single level signals, perform a predefined operation on the single level signals to generate an output signal, and compensate for timing skew between the n multi-level signals, using the single level signals. The n and m are natural numbers, where n>=2 and m>=3.
