  • Patent number: 10595822
    Abstract: A test for screening defects of a transmission/reception circuit in an IC is enabled at low cost, without withstand voltage violation, and without carrying out electrical contacts with many terminals connected to oscillators. In a transmission/reception separation switch circuit using transistors as switch elements, a potential of a gate is lowered in a test more than the potential in a case of reception to avoid gate-source withstand-voltage violation when a large-amplitude signal is input, and an internal-signal loopback test is carried out without destroying a reception circuit.

  • Patent number: 10517570
    Abstract: A transmit receive switch circuit has a first MOSFET (MN1) and a second MOSFET (MN2), goes into a switch-off state at the time of transmission, and goes into a switch-on state at the time of reception. The first MOSFET (MN1) and the second MOSFET (MN2) are connected between an input terminal (SWIN) and an output terminal (SWOUT). The switch circuit includes a shunt circuit (SHNT) that is connected between a common gate (COMG) and a common source (COMS), the common gate being connected to the gates of the first and second MOSFETs, and the common source being connected to the sources of the first and second MOSFETs. When a signal having a negative voltage relative to a reference voltage is applied to the input terminal, a switch that temporarily turns on causes the shunt circuit to short-circuit the common gate and the common source.
