    摘要: The continuous conduction mode (CCM) boost voltage power factor correction apparatus with an average-current control mode of the present invention uses resettable integrators to integrate the difference voltage signal outputted from the voltage error amplifier and the input current signal obtained from detection. The integration results are then compared to control the duty cycle of the switch. Thereby, the input current and the input voltage in the AC/DC electrical power converter have a proportion relation and their phases are the same as each other. The components used in this control method are simpler than the PFC circuit of the prior art. It is easy to integrate in one chip with fewer pins. The apparatus of the present invention has a high power factor and a low total harmonic distortion (THD).

    摘要: A high-speed PWM control apparatus with adaptive voltage position and a driving signal generating method thereof is provided. The present invention automatically detects a change in the loading and adjusts the voltage position instantaneously for stabilizing the voltage and reducing the loading output power consumption. The present invention does not require a clock signal to generate a driving signal and does not require an error amplifier to control the modulation. Therefore, the present invention has a fast transient response that responds to the change of the loading instantaneously and has a stabilizing effect. When the apparatus is on a continuous conduction mode (CCM), the switching frequency of the controller is still fixed even though the input voltage Vin and the output voltage Vout are changed. The electrical-magnetic noise disturbance is improved.

    摘要: A frequency jitter generator and a frequency jitter PWM controller are provided for overcoming the shortcoming that a conventional PWM controller reduces the electromagnetic interference issue by means of varying the operating frequency of the PWM controller based on an input voltage, while resulting in the uncertainty of the range of frequency jitter and the difficulty circuit design due to the effect of the input voltage and the load. The frequency jitter generator and PWM controller adjust the range of frequency jitter by using a signal within a fixed voltage range. The invention not only gets rid of the effect of the input voltage and the loading, but also simplifies the circuit design by fixing the range of frequency jitter no greater than a predetermined percentage regardless of the operating frequency of the PWM controller.

    摘要: A method to reduce the inverse narrow width effect in NMOS transistors is described. An oxide liner is deposited in a shallow trench that is formed to isolate active areas in a substrate. A photoresist plug is formed in the shallow trench and is recessed below the top of the substrate to expose the top portion of the oxide liner. An angled indium implant through the oxide liner into the substrate is then performed. The plug is removed and an insulator is deposited to fill the trenches. After planarization and wet etch steps, formation of a gate dielectric layer and a patterned gate layer, the NMOS transistor exhibits an improved Vt roll-off of 40 to 45 mVolts for both long and short channels. The improvement is achieved with no degradation in junction or isolation performance. The indium implant dose and angle may be varied to provide flexibility to the process.

    摘要: Dynamic Random Access Memory (DRAM) cells are formed in a P well formed in a biased deep N well (DNW). PMOS transistors are formed in N wells. The NMOS channels stop implant mask is modified not to be a reverse of the N well mask in order to block the channels stop implant from an N+ contact region used for DNW biasing. In DRAMs and other integrated circuits, a minimal spacing requirement between a well of an integrated circuit on the one hand and adjacent circuitry on the other hand is eliminated by laying out the adjacent circuitry so that the well is located adjacent to a transistor having an electrode connected to the same voltage as the voltage that biases the well. For example, in DRAMs, the minimal spacing requirement between the DNW and the read/write circuitry is eliminated by locating the DNW next to a transistor precharging the bit lines before memory accesses. One electrode of the transistor is connected to a precharge voltage. This electrode overlaps the DNW which is biased to the same precharge voltage. This electrode provides the DNW N+ contact region.
