  • Patent number: 9455711
    Abstract: A semiconductor integrated circuit device that has a high-voltage analog switch circuit and is operable at a low power-supply voltage, and which has a first high-voltage MOSFET HN1, a second high-voltage MOSFET, and a first floating gate voltage control circuit. The first floating gate voltage control circuit operates at a voltage of 5 V or lower, and when turning on the first high-voltage MOSFET and the second high-voltage MOSFET, the first floating gate voltage control circuit sets a voltage in the source terminal of the first high-voltage MOSFET as a reference voltage, adds a floating voltage corresponding to the power-supply voltage to the reference voltage, and supplies the added voltage to the gate terminals of the first high-voltage MOSFET and the second high-voltage MOSFET.

  • Patent number: 9337823
    Abstract: Provided is a switching circuit capable of transmitting a signal with large amplitude and large current while suppressing deterioration when a small-amplitude signal is transmitted. The switching circuit 100 includes a first terminal a, a second terminal b, a first switch 1, a second switch 2, a first separation switch 3a, and a second separation switch 3b. The first switch 1 connects the first terminal a and the second terminal b according to a control signal. The second switch 2 has a first node n1 and a second node n2, and connects between the nodes in synchronization with the first switch 1. The first separation switch 3a transmits a signal of the first node n1 to the second node n2 when an electric potential of the first node n1 is higher than that of the second node n2 by more than a predetermined electric potential.
