Abstract: A monitoring signal generation circuit of a SPS and method thereof is disclosed. The SPS provides an output current. The monitoring signal generation circuit provides a current monitoring signal related to the output current. The monitoring signal generation circuit includes a simulation current circuit and a control circuit. The simulation current circuit receives a reference voltage and provides a simulation current signal or the reference voltage as the current monitoring signal. The control circuit is coupled to the simulation current circuit and configured to receive the reference signal, the current monitoring signal and an indication signal. During a period when the indication signal indicates that power switches of the SPS are turned off, the control circuit controls the simulation current generation circuit to provide the simulation current signal or the reference voltage as the current monitoring signal according to the current monitoring signal and the reference voltage.

Abstract: A protective structure and an electronic device using the same are disclosed. The electronic device includes a first housing member, a second housing member, a blocking unit, and an operating module. The second housing member faces the first housing member, wherein a slit is located at the periphery of an enclosure disposed between the first and second housing members. The blocking unit, having a shape compatible with the shape of the slit, is disposed therein and includes a sealing member and a first foamable material. The sealing member is compressed by the first and second housing members, and the first foamable material is formed in the slit along an extending direction of the sealing member.
