摘要： A charge pump includes a switching circuit which is interposed among first and second output capacitors, a flying capacitor, and an input power supply; and a control unit which controls the switching circuit. The charge pump is operated in an operation mode including a high-voltage outputting mode, a low-voltage outputting mode, and a relay mode. The control unit controls the switching circuit so that respective charging voltages of the first and second capacitors that are charged in the high-voltage outputting mode are gradually lowered. The control unit changes the operation mode of the charge pump by relay transition from the high-voltage outputting mode through the relay mode to the low-voltage outputting mode when a voltage lower command is given during a period when the operation mode of the charge pump is in the high-voltage outputting mode.

摘要： A pseudo-stereo circuit is provided which processes an input monophonic signal into stereophic audio signals. A phase-shift circuit shifts a phase of the input monophonic signal by a phase shift amount that depends upon a frequency of the monophonic signal, to produce an output signal having a gain with respect to the input monophonic signal which is equal to or larger than a predetermined level over an entire frequency band thereof, and reaches a peak at a frequency at which the phase shift amount of the output signal with respect to the input monophonic signal assumes a value equal or closer to −&pgr;. A mixing circuit produces a first mixed signal by mixing a signal obtained by inverting a phase of the output signal of the phase-shift circuit with the input monophonic signal by a first mixing ratio, and produces a second mixed signal obtained by mixing the output signal of the phase-shift circuit with the input monophonic signal by a second mixing ratio. The mixing circuit generates the first mixed signal as a first audio signal carried by one of left and right channels that provide stereophonic audio signals, and generates the second mixed signal as a second audio signal carried by the other of the left and right channels.

摘要： A sound field processor having amplitude/phase conversion circuits for left and right channels of a stereophonic signal. The amplitude/phase conversion circuits for left and right channels have substantially the same circuit structure. Each of the amplitude/phase conversion circuits has an inversion amplifier, an amplitude/phase characteristic changing circuit that changes amplitude and phase characteristics of an output from the inversion amplifier, and a feedback device that add outputs from the amplitude/phase characteristic changing circuit and outputs from the inversion amplifier to an input signal to generate a sum signal and feed back the sum signal to the inversion amplifier. An output from the inversion amplifier for the left channel and an output from the amplitude/phase characteristic changing circuit for the right channel are added by a first adder device. An output from the inversion amplifier for the right channel and an output from the amplitude/phase characteristic changing circuit for the left channel are added by a second adder device. An output from the amplitude/phase characteristic changing circuit is fed back through a feedback path between an output and an input of the amplitude/phase characteristic changing circuit. A D/A converter is interposed in the feedback path to adjust the level of the feedback signal to perform bass control.
