摘要： A power supply device includes a transformer including a primary winding, a secondary winding and an auxiliary winding, first, second and third circuits, and a switch. The first circuit in which a first capacitor and a first rectifier are connected in series is connected to the primary winding in parallel. The switch of which one end is connected to one end of the primary winding. The second circuit in which the auxiliary winding and a second rectifier are connected in serial is connected between a connecting point, to which the first capacitor and the first rectifier are connected, and the other end of the switch. The third circuit including a resistor and a third rectifier is connected to a gate of the switch. In the third circuit, a resistance value in a direction where a current flows into the gate of the switch is smaller than that in a direction where the current flows out of the gate.

摘要： A radio frequency switch circuit includes a series circuit. The series circuit includes a first series connection group and a second series connection group. The first series connection group includes a plurality of first transistors. The second series connection group includes a plurality of second transistors. Control terminals of the first transistors are all coupled to a first control node. Control terminals of the second transistors are all coupled to a second control node. When an electrostatic discharge event occurs, a voltage at the first control node is different from a voltage at the second control node. In a normal operation state, a switch state of the first series connection group and a switch state of the second series connection group are the same as each other.
