摘要： A method for calculating current position coordinate and a method for calculating a pseudo range are applied to a global positioning system (GPS) receiver. A position coordinate of the GPS receiver at the positioning time point is calculated through an average pseudo range between the GPS receiver and each satellite at a positioning time point. With regard to calculating the average pseudo range between the GPS receiver and each satellite, for each satellite, original pseudo ranges are obtained through calculating a pseudo range between the satellite and the GPS receiver at each millisecond (ms) in a time range including the positioning time point, and then the average pseudo range between the satellite and the GPS receiver at the positioning time point is obtained through calculating an average value of the obtained original pseudo ranges between the GPS receiver and the satellite.

摘要： In this invention a process for a flash memory cell and an architecture for using the flash memory cell is disclosed to provide a nonvolatile memory having a high storage density. Adjacent columns of cells share the same source and the source line connecting these sources runs vertically in the memory layout, connecting to the sources of adjacent columns memory cells. Bit lines connect to drains of cells in adjacent columns and are laid out vertically, alternating with source lines in an every other column scheme. Wordlines made of a second layer of polysilicon form control gates of the flash memory cells and are continuous over the full width of a memory partition. Programming is done in a vertical page using hot electrons to inject charge onto the floating gates. the cells are erased using Fowler-Nordheim tunneling of electrons from the floating gate to the control gate by way of inter polysilicon oxide formed on the walls of the floating gates.

摘要： In fabricating a bipolar transistor, semiconductor dopant is introduced into a semiconductor body during a base doping operation to define a doped region, that forms a PN junction with adjoining semiconductor material and abuts a slanted sidewall of a field insulating region. The doped region constitutes a base region for the transistor. The base doping operation entails ion implanting the dopant into the body at a tilt angle of at least 15.degree. relative to the vertical. The minimum lateral base thickness and, the minimum sidewall base thickness increase relative to the minimum vertical base thickness. As a result, the magnitude of the collector-to-emitter breakdown voltage typically increases. The minimum lateral, sidewall, and vertical base thicknesses vary with the tilt angle and base-implant energy in such a manner that the minimum lateral base thickness and the minimum sidewall base thickness are separately controllable from the minimum vertical base thickness.

摘要： A bipolar transistor is fabricated by a process in which first and second dopants of the same conductivity type are introduced into a semiconductor body through at least partially overlapping sections, preferably the same section, of the body's upper surface to form an emitter. The first dopant is introduced at a greater dosage than the second dopant such that the emitter consists at least of a main emitter region constituted primarily with the first dopant. The introduction of the second dopant into the body entails ion implanting the second dopant at a tilt angle of at least 15.degree. relative to a direction generally perpendicular to the body's upper surface. Part of the second dopant is so implanted into an extension zone that extends laterally beyond the main emitter region. The extension zone may be of the same conductivity type as, or of opposite conductivity type to, the main emitter region. In either case, the extension zone is lightly doped and reduces transistor performance degradation by reducing the electric field along the emitter-base junction, especially along the upper semiconductor surface.

摘要： A method for obtaining correct phase inversion points in a signal of global positioning system (GPS) includes the following steps. A satellite signal from one of a plurality of satellites is received continuously. A plurality of phase inversion points in the received satellite signal is interpreted. Each time difference between each two adjacent phase inversion points among the plurality of phase inversion points is calculated. It is determined whether each of the time differences is an integral multiple of 20 milliseconds. A data is retrieved every 20 milliseconds from the satellite signal by using a first phase inversion point in the plurality of phase inversion points as a starting point when each of the time differences is an integral multiple of 20 milliseconds. By finding out a plurality of correct phase inversion points in the satellite signal, the positioning speed is increased, and thus a positioning time required is reduced.

摘要： A method for obtaining a precise sampling frequency of a global positioning system (GPS) is applied in a GPS receiver. First, a radio frequency (RF) module of the GPS receiver is used to receive a satellite signal from at least one satellite. Then, a plurality of code delays of the satellite signal is calculated at a fixed time interval, and time differences between all adjacent two code delays among all the obtained code delays are calculated to obtain a plurality of time differences. Next, a mean value of all the obtained time differences is calculated. At last, a ratio between 1000 times of the mean value and the fixed time interval is calculated to obtain an error value, and the error is added to a standard sampling frequency of the RF module to obtain a new sampling frequency.
