摘要： An amplification system of the invention can decrease power consumption in a power amplification section if the power amplification section need not be used. The power consumption in the power amplification section can be decreased by shutting off power feed into a voltage amplification stage by a power control section, and the power feed state into a power amplification stage from a power supply section is not changed. Thus, power feed into the voltage amplification stage of the circuit wherein a large current does not flow needs only to be controlled using limiter means also used for a different application, so that the power consumption of the power amplification section can be decreased without the need for enlarging the circuit scale, with saved space, and simply.

摘要： A complementary signal generating circuit (301) generates first complementary signals (S1, S2) from a PWM signal. A signal converting circuit (302) converts the first complementary signals to second complementary signals (S3, S4 or S5, S6) having a voltage component based on a negative power supply (VPP−). Among the second-complementary signals, the signals (S3, S4) are supplied to a driving circuit (305), and the signals (S5, S6) are supplied to a current driving circuit (303). In response to the signals (S5, S6), the current driving circuit outputs third complementary signals (H3, H4) having a current component that is directed toward the negative power supply (VPP−), to a driving circuit (304). As a result, the driving circuits (304, 305) complementarily drive power-MOS transistors (401, 402).

摘要： An operational amplifier has a differential amplifier stage comprising a pair of first PMOS transistors for inputting signals, which are arranged between a positive voltage supply coupled with a first constant current source and a negative voltage supply, wherein second PMOS transistors of a high voltage resistant type, gates of which are biased to a prescribed voltage, are arranged on current paths lying between the first PMOS transistors and the negative voltage supply together with load resistors. Herein, each of drain voltages of the first PMOS transistors is limited to a certain value that is higher than the prescribed voltage by a gate threshold voltage. Therefore, even when the first PMOS transistors are configured of a normal voltage resistant type, it is possible to reliably prevent voltages applied to the first PMOS transistors from exceeding breakdown voltages thereof, thus avoiding unnecessary reduction of an S/N ratio.

摘要： Differential integrator circuit integrates a differential between a difference between a signal supplied from a first signal source and a feedback signal of amplifier output and a difference between a signal supplied from a second signal source and a feedback signal of the amplifier output. The signal supplied from the second signal source is opposite in phase from the signal supplied from the first signal source. Thus, the integrator circuit outputs two integrated signals of different polarities. Comparator compares the two integrated signals from the integrator circuit to thereby output a PWM signal. First driver circuit amplifies the PWM signal and outputs the amplified PWM signal with inverted phase, and a second driver circuit amplifies the PWM signal and outputs the amplified PWM signal with noninverted phase. First switching circuit is driven by the output of the first driver circuit, while a second switching circuit is driven by the output of the second driver circuit.
