摘要:
A system for supplying an operating voltage to a CPU (50) includes a power supply (10) for supplying power to a computer, a PWM controller (30), a feedback circuit (70), and a plurality of electronic elements. The PWM controller converts voltage supplied to the computer to an operating voltage of the CPU. The feedback circuit comprises a plurality of resistors and capacitors, and feeds back a feedback voltage to the PWM controller. The feedback circuit further includes a thermistor. When resistance of the resistors is changed due to surrounding temperature changing, the thermistor equalizes the resistance changing.

The present application discloses a feed-forward amplifier device and the method thereof. The device comprises: a splitter for splitting an input signal into two portions; a non-linear amplifier for amplifying the input signal and producing inter-modulation products; a carrier canceling unit for generating pure inter-modulation products; a linear amplifier for amplifying the pure inter-modulation products; and a coupler for generating final output signal by counteracting the inter-modulation products with the amplified pure inter-modulation products; wherein the splitter and the carrier canceling unit are provided in digital base band. According to the present disclosure, pure inter-modulation products can be generated and adjusted more flexibly and more accurately in digital base band, and hence ideal output signal may be generated.
