  • Level shifter system and capacitive-coupled level shifter
    Patent number: 11329636
    Abstract: A capacitive-coupled level shifter includes a capacitive divider circuit having a first capacitive divider branch configured to couple a first input terminal to a first comparator terminal and a second capacitive divider branch configured to couple a second input terminal to a second comparator terminal. The first capacitive divider branch and the second capacitive divider branch are symmetric so as to cancel out a common mode voltage of a modulated signal input to the capacitive divider circuit. A level shifter system which includes the capacitive-coupled level shifter is also described.

  • Capacitive-coupled level shifter and related system
    Patent number: 10749509
    Abstract: A capacitive-coupled level shifter includes: an input having a positive input terminal and a negative input terminal, the input configured to receive a modulated signal in a first voltage domain; a comparator circuit configured to shift the modulated signal to a second voltage domain higher than the first voltage domain; and a capacitive divider circuit comprising a first capacitive divider branch coupling the positive input terminal of the input to a positive input terminal of the comparator circuit and a second capacitive divider branch coupling the negative input terminal of the input to a negative input terminal of the comparator circuit. The first capacitive divider branch and the second capacitive divider branch are symmetric so as to cancel out a common mode voltage of the modulated signal. A level shifter system which includes the capacitive-coupled level shifter is also described.
