    Abstract: Disclosed are a housing for receiving an electronic device and an electronic system having the same. The electronic system includes a case having lower and upper cases detachably combined with the lower case, a circuit board arranged in an inner space of the case and secured to the lower case such that at least a grounding line and at least a connection line are provided with the circuit board, a plurality of devices arranged on the circuit board such that each device is separated from one another by the grounding line and is connected with one another by the connection line, and at least an electromagnetic shielding member embedded onto the upper case such that the electromagnetic shielding member is in contact with the grounding line around the device to provide a shielding space receiving the device. The device is protected from unexpected electromagnetic waves by the electromagnetic shielding member.

    Abstract: A power supply circuit includes a first comparator, a second comparator, a first voltage regulator, an output terminal, a first path and a second path. The first comparator compares a first input voltage with a first reference voltage to generate a first control signal. The second comparator compares a second input voltage with the first reference voltage to generate a second control signal. A voltage level of the second input voltage is different from a voltage level of the first input voltage. The first voltage regulator is selectively enabled based on the first control signal and the second control signal, and generates a first voltage based on the first input voltage. A voltage level of the first voltage is substantially the same as the voltage level of the second input voltage. The output terminal is configured to output one of the second input voltage and the first voltage as a power supply voltage. The first path directly provides the first input voltage to the first voltage regulator. The second path directly provides the second input voltage to the output terminal. The second input voltage bypasses the first voltage.
