The present disclosure generally relates to a PWM comparator and a class D amplifier. The PWM comparator described above introduces current feedback mechanism, basing the waveform state of received high frequency triangle signal and the level state of output signal of the PWM comparator, the hysteresis is changing dynamically. In the same resolution, the noise resistance ability of the PWM comparator described above is much better than that of the conventional PWM comparators which has a fixed hysteresis, thus the PWM comparator can work stably even if the duty cycle of output signal is nearly 100%.

An embedded capacitor substrate module includes a substrate, a metal substrate and a solid electrolytic capacitor material. The solid electrolytic capacitor material is formed on the metal substrate, so as to form a solid electrolytic capacitor with the substrate. The embedded capacitor substrate module further includes an electrode lead-out region formed by extending the substrate and the metal substrate. The metal substrate serves as a first electrode, and the substrate serves as a second electrode. An insulating material is formed between the substrate and the metal substrate. Therefore, the embedded capacitor substrate module is not only advantageous in having a large capacitance as the conventional solid capacitor, but also capable of being drilled or plated and electrically connected to other circuits after being embedded in a printed circuit board.

A package carrier suitable for carrying at least one light emitting device and at least one light receiving device includes a carrier substrate and a metal sheet. The carrier substrate includes a first carrying area and a second carrying area. The light emitting device is disposed in the first carrying area and the light receiving device is disposed in the second carrying area. The metal sheet is disposed in the carrier substrate and located between the first carrying area and the second carrier area, for blocking optical signal transmission between the light emitting device and the light receiving device.
摘要:
The invention provides a method for power management for a computer system. In one embodiment, the computer system comprises a system controller, a chipset, and a battery coupled to the chipset via a system management bus. First, a timer of the chipset is used to calculate an accumulated time value. When the accumulated time value exceeds a threshold value, the chipset is directed to send a system control interrupt to the system controller. After the system controller receives the system control interrupt, the system controller is triggered to detect a power level supplied by the battery via the system management bus.

Pro-apoptotic signaling caused by down-modulation of KIAA0358 or expression of IG20-SV4 effectively induces spontaneous apoptosis and sensitization to TNFα-induced apoptosis in neuroblastoma cells. Methods and composition to enhance cell death in neuroblastoma are provided. Methods and compositions to reduce cell death in neurodegenerative disorders are provided.
摘要:
Improving the timing and/or yield of a circuit design is disclosed. Timing and yield improvements are often competing objectives in circuit design since timing improvements typically result from reducing capacitive couplings and yield improvements typically increase capacitive couplings. Trade-offs between timing and yield improvements are consequently part of the circuit design and/or optimization process.
