摘要： the output amplifiers requiring a bias voltage can be activated or deactivated individually, and a bias acceleration circuit for rapidly increasing the magnitude of a bias voltage in time can be provided in or with the bias circuit, whereby even in case of the capacitance of the capacitor included in the bias circuit being increased for improving the power supply rejection ratio (PSRR), the rise in the bias voltage can be increased so that the pop sound which arises when the bias circuit is activated can be still diminished.

摘要： In a converter which operates in a serial-parallel manner and performs analog-to-digital (A/D) conversion, the number of high bits is made more than half the entire number of bits, with the number of low bits is given by half the entire number of bits, thereby acquiring high-bit and low-bit data. When no match exists between the high-bit data and the low-bit data, the high-bit data can be modified by means of the low-bit data.

摘要： A charging circuit receives electric power from a solar battery, and charges a secondary battery. A charging current detection unit generates a detection signal that corresponds to a charging current supplied from a DC/DC converter to the secondary battery. A control circuit generates a reference voltage that corresponds to the detection signal. A driving unit generates a pulse signal having a duty ratio that is adjusted such that the voltage output from the solar battery matches the reference voltage, and performs switching of a switching transistor according to the pulse signal. A control circuit adjusts the reference voltage such that the reference voltage becomes greater.

摘要： A power supply adapter receives an AC voltage, converts the AC voltage into a DC voltage, and supplies the DC voltage to an electronic device. A DC/DC converter converts the voltage smoothed by a smoothing capacitor into the DC voltage. A device-side connector is connected to the DC/DC converter via a cable, and is configured to be detachably connected to the electronic device. The device-side connector includes a detection unit detecting whether or not the electronic device is connected, and generates a connection detection signal indicating whether or not the electronic device is connected. A control circuit of the DC/DC converter is connected to the detection unit of the device-side connector via the cable, and is set to an operating state when the connection detection signal indicates that the electronic device is connected, and is set to a non-operating state when the connection detection signal indicates that the electronic device is not connected.
