    Abstract: A semiconductor chiplet device includes a package substrate, an interposer layer, a first die and a second die. The first die includes a first interface, and the second die includes a second interface. A first side of the interposer layer is configured to arrange the first die and the second die. The first die and the second die perform a data transmission through the first interface, the interposer layer and the second interface. The package substrate is arranged on a second side of the interposer layer, and includes a decoupling capacitor. The decoupling capacitor is arranged between the first interface and the second interface, or arranged in a vertical projection area of the first interface and the second interface on the package substrate.

    Abstract: A digital-to-analog converter and an operation method thereof are provided. The digital-to-analog converter includes a current source module, a decoder, a change indicator, and a random number generator. The decoder is coupled to the current source module and receives a digital input signal. The change indicator is coupled to the decoder and provides an indication signal to the decoder. The random number generator is coupled to the change indicator and provides a random number signal to the change indicator. The change indicator generates an indication signal according to the random number signal, and the decoder generates a control signal to the current source module according to the digital input signal and the indication signal, so that the current source module generates an analog output signal corresponding to the digital input signal according to the control signal.

    Abstract: A communication system and an operation method thereof are provided. A transmitting device transmits a data unit to a receiving device through a data channel of a communication interface. The transmitting device calculates an original verification information unit of the data unit and synchronously transmits the original verification information unit to the receiving device through a verification information channel of the communication interface based on a transmission timing of the data unit in the data channel. After receiving a current data unit and before receiving a next data unit, the receiving device verifies whether the current data unit received from the data channel has errors in real time based on a current original verification information unit corresponding to the current data unit.

    Abstract: An analog-to-digital converting device includes N-stage first analog-to-digital converters (ADCs), a second ADC, a first calibration circuit, a data recovery circuit and an output circuit. The N-stage first ADCs has a first sampling frequency that is (N+1)/N times of a second sampling frequency, and converts an input signal into first quantized outputs. The second ADC has the second sampling frequency, and converts the input signal into a second quantized output. The first calibration circuit calibrates offsets of the first quantized outputs and the second quantized output to generate third quantized outputs and a fourth quantized output. The data recovery circuit outputs, by the second sampling frequency, one of the third quantized outputs as a fifth quantized output, and subtracts the fifth quantized output from the fourth quantized output to generate output data. The output circuit generates an output signal according to the third quantized outputs and the output data.

    Abstract: An electrostatic discharge (ESD) protection device includes a first clamping circuit, a second clamping circuit, and a diode circuit. The first clamping circuit is coupled between a first power rail and a second power rail. The second clamping circuit is coupled between a third power rail and the second power rail. The diode circuit is configured to steer an ESD current from an input/output pad to at least one of the first clamping circuit or the third power rail. The first power rail receives a first voltage, the second power rail receives a second voltage, the third power rail receives a third voltage, the third voltage is higher than the first voltage, and the first voltage is higher than the second voltage.
