  • Publication number: 20230006652
    Abstract: A transmission-end impedance matching circuit operates according to a signal of an overvoltage signal source and includes a first level shifter, a voltage generating circuit, and an impedance matching circuit. The first level shifter generates a first conversion voltage according to a source signal and operates between a first high voltage and a ground voltage. The voltage generating circuit generates a second high voltage according to the first conversion voltage, the first high voltage, and a medium voltage. The impedance matching circuit includes a second level shifter, a transistor, and two resistors. The second level shifter generates a gate voltage according to the second high voltage, a low voltage, and an input signal. The transistor is turned on/off according to the gate voltage and has a withstand voltage lower than the first high voltage. Each of the two resistors is coupled between the transistor and a differential signal transmission end.

  • Publication number: 20230006660
    Abstract: A level shifter can achieve a level shift by a wide margin. The level shifter includes a latch circuit, a clamping circuit, a protection circuit, and an input circuit. The latch circuit is coupled between a high-voltage terminal and a pair of output terminals for outputting a pair of output signals. The clamping circuit is coupled between a medium-voltage terminal and the pair of output terminals and limits the minimum voltage of the pair of output signals to the medium voltage. The protection circuit is set between the latch circuit and the input circuit, and prevents an excessive voltage drop between the input circuit and the pair of output terminals. The input circuit includes an input transistor pair coupled between the protection circuit and a low-voltage terminal having a low voltage. The input transistor pair receives a pair of input signals and operates accordingly.
