Abstract: A chiplet system with an auto-swapping function and a signal communication method thereof are provided. The chiplet system at least includes a first chiplet and a second chiplet. The signal communication method includes the following steps. The first chiplet and the second chiplet are electrified. The first chiplet and the second chiplet are reset and driven. Through a serial number information, the first chiplet and the second chiplet are identified. A handshaking communication procedure is executed by the first chiplet and the second chiplet to confirm whether a pin connection relationship between the first chiplet and the second chiplet is correct. If the pin connection relationship between the first chiplet and the second chiplet is incorrect, pin function switching is performed by the first chiplet or the second chiplet.

Abstract: A semiconductor device package has two integrated circuits. Each of the two integrated circuits has a core circuit and a digital input/output (I/O) interface circuit. The core circuits of the two integrated circuits are powered by two different core voltages, and the I/O circuits of the two integrated circuits are powered by the same core voltage selected from the two different core voltages.

Abstract: A temperature sensing device includes a bandgap voltage generator, N mirror current sources, a temperature voltage generator, and a temperature calculating unit. The mirror current sources mirror N mirror currents according to a positive temperature coefficient current. The temperature voltage generator sets the conducting number M of the mirror current sources based on a control signal, so as to generate a temperature voltage. The temperature calculating unit gradually counts the control signal and compares a potential of the temperature voltage with a potential of a reference voltage generated by the bandgap voltage generator after counting the control signal, so as to calculate and obtain temperature information. Thus, the temperature sensing device controls the conducting number M of the mirror current sources to generate the temperature voltage instead of applying serially-connected resistors, so as to reduce a circuit area of the temperature sensing device and reduce noise.

Abstract: A line driver includes the following. A current replication unit replicates a reference current according to an input signal. A current mapping unit adjusts a number of P channel transistors connected in parallel and inside the current mapping unit according to control information, so as to amplify the reference current according to a magnification value. A first resistor is electrically connected between the current replication unit and a direct-current voltage. A second resistor is electrically connected to the current replication unit and the current mapping unit and generates an output signal. A signal detection unit performs integration on a part of a difference between the input signal and the output signal, thereby generating an integration signal. A magnification control unit gradually adjusts magnification information related to a reference signal, and updates the control information by the magnification information when the reference signal is equal to the integration signal.
