摘要： A circuit including a charge pump and regulation circuitry is described. The output of the charge pump is connected to provide a first output signal that is connectable to drive a load. A diode is connected to provide a second output signal of lower voltage from the first output signal. The regulation circuitry is connected to the second output level and is connectable to the charge pump to regulate its output. The circuit also includes a current source connectable from the second line to ground, where control circuitry connects the current source to the second line when the first line is connected to the load.

摘要： Techniques of providing a low output voltage, high current capability charge pump are given. The charge pump has multiple capacitors along with switching circuitry. In an initialization phase, the first plate of each of the capacitors is connected to receive a regulator voltage and the second plate of each capacitor is connected to ground. In a transfer phase, the capacitors are connected in series, where, for each capacitor after the first, the second plate is connected to the first plate of the preceding capacitor in the series. The output voltage of the pump is from the first plate of the last capacitor in the series. Regulation circuitry generates the regulator voltage from a reference voltage to have a value responsive to the output voltage level of the pump.

摘要： A circuit and corresponding method for providing a reference voltage are presented. The circuit includes a current source having a magnitude with positive temperature correlation connected to a node, and a diode element connected between the node and ground, where the reference voltage is provided from the node. The circuit also includes a variable resistance connected to receive an input indicative of the circuit temperature and through which the diode element is connected to the node. The value of the variable resistance is adjusted based upon the circuit temperature input. The circuit is useful for application as a peripheral circuitry, such as on a flash or other non-volatile memory and other circuits requiring an on-chip reference voltage source.

摘要： A charge pump system is formed on an integrated circuit that can be connected to an external power supply. The system includes a charge pump and a clock generator circuit. The clock circuit is coupled to provide a clock output, at whose frequency the charge pump operates and generates an output voltage from an input voltage. The clock frequency is a decreasing function of the voltage level of the external power supply. This allows for reducing power consumption in the charge pump system formed on a circuit connectable to an external power supply.

摘要： A system for encoding a video stream into a processed video signal that includes at least one image, includes a pattern detection module for detecting a pattern of interest in the at least one image and identifying a region that contains the pattern of interest when the pattern of interest is detected, based on an analysis of the image in a plurality of domains. An encoder section, generates the processed video signal and wherein, when the pattern of interest is detected, a higher quality, such as a higher bit allocation or higher computational processing, is assigned to the region than to portions of the at least one image outside the region.

摘要： In a nonvolatile memory array that stores randomized data, the program level—the number of states per cell stored in a population of memory cells—may be determined from the aggregated results of a single read step. A circuit for aggregating binary results of a read step includes parallel transistors with control gates connected to the data latches holding the binary results, so that current flow through the combined transistors depends on the binary results.

摘要： A charge pump circuit for generating an output voltage is described. Charge pump circuits typically have two branches. As the clocks supplying the branches of a charge pump circuit alternate, the output of each branch will alternately provide an output voltage, which are then combined to form the pump output. The techniques described here allow charge to be transferred between the two branches, so that as the capacitor of one branch discharges, it is used to charge up the capacitor in the other branch. An exemplary embodiment using a voltage doubler-type of circuit, with the charge transfer between the branches accomplished using a switch controller by a boosted version of the clock signal, which is provided by a one-sided voltage doubler.
