1. A circuit comprising:

  • a first capacitive device;

    a first latch;

    a second capacitive device;

    a second latch; and

    a first circuit,whereinthe first capacitive device includes a first end and a second end;

    the first end is configured to receive a first input signal;

    the first latch includes a first transistor and a second transistor;

    the first transistor and the second transistor are of a first type;

    a first terminal of the first transistor and a first terminal of the second transistor are configured to receive a first voltage value;

    a second terminal of the first transistor is coupled with a third terminal of the second transistor;

    a third terminal of the first transistor is coupled with a second terminal of the second transistor and with the second end of the capacitive device, and is configured to provide an output voltage for the first latch;

    the second capacitive device includes a first end and a second end;

    the first end of the second capacitive device is configured to receive the first input signal;

    the second latch includes a third transistor and a fourth transistor;

    the third transistor and the fourth transistor are of a second type different from the first type;

    the second end of the second capacitive device is coupled with the second latch; and

    the first circuit is coupled between the second end of the first capacitive device and the second end of the second capacitive device.
