Abstract: A transmitter circuit includes a clock generator configured to generate a plurality of clock signals having different phases, and a plurality of selection circuits configured to receive a plurality of parallel data signals and output a serial data signal on an output node based on the plurality of clock signals and the received plurality of parallel data signals. Each of the plurality of selection circuits includes a data multiplexer configured to generate a plurality of data selection signals based on the received one of the plurality of parallel data signals and the plurality of clock signals; a control signal generator configured to generate first and second control signals based on the plurality of data selection signals; and an output driver connected to the output node, and configured to precharge the output node based on the first control signal or discharge the output node based on the second control signal.

Abstract: A multi-level signal receiver includes a data sampler circuit and a reference voltage generator circuit. The data sampler includes (M−1) sense amplifiers which compare a multi-level signal having one of M voltage levels different from each other with (M−1) reference voltages. The data sampler generates a target data signal including N bits, M is an integer greater than two and N is an integer greater than one. The reference voltage generator generates the (M−1) reference voltages, At least two sense amplifiers of the (M−1) sense amplifiers have different sensing characteristics.

Abstract: A multi-mode transmission line includes a first and second conductive layers, first and second waveguide walls, a strip line, and a blind conductor. The second conductive layer that is formed over the first conductive layer. The first waveguide wall is elongated in a first direction and is in contact with the first conductive layer and the second conductive layer in a vertical direction. The second waveguide wall is elongated in the first direction parallel to the first waveguide wall and is in contact with the first conductive layer and the second conductive layer in the vertical direction. The strip line is formed between the first and second conductive layers and between the first and second waveguide walls. The blind conductor is connected to one of the first conductive layer, the second conductive layer, the first waveguide wall, or the second waveguide wall.
