Semiconductor device and wireless communication device

A wireless communication device including:

• a Radio Frequency (RF) switch circuit including a common terminal configured to couple with an antenna and a plurality of ports, including:
• a plurality of switch circuits coupled between the antenna and the plurality of ports, and
• an interface (I/F) circuit coupled between a first power supply and a second power supply, and configured to control the plurality of switch circuits,
• a power-on reset circuit configured to provide a power-on reset signal to control the I/F circuit;
• a transmitter circuit coupled with one of the plurality of ports;
• a receiver circuit coupled with another one of the plurality of ports;
• wherein the power-on reset circuit comprises:
• a first diode and a second diode coupled in parallel in a forward direction between the first power supply and the second power supply;
• a first resistor circuit and a first capacitor element coupled in parallel between the first diode and the first power supply;
• a second resistor circuit and a second capacitor element coupled in parallel between the second diode and the first power supply;
• and
• a comparator circuit configured to output a comparison result between a first voltage of a first node of the first resistor circuit and a second voltage of a second node of the second resistor circuit as the power-on reset signal.
