摘要： A receiver receiving global positioning data from one or more satellites above the Earth's surface detects a change in at least one parameter associated with the receiver and determines if the change is to be treated as erroneous. As a result of determining if the change in the at least one parameter is to be treated as erroneous, a further action may be performed. Determining if the change is to be treated as erroneous may include, for example, detecting changes in more than one parameter and determining if the changes are coincident. Detecting the change may also enable the receiver to predict the presence and magnitude of multipath components of signals, predict changes in an environment local to the receiver, predict large errors in position estimates determined by the receiver and modify an acquisition and tracking strategy used by the receiver.

摘要： A method of providing an impedance match for an integrated semiconductor circuit to other microwave elements is provided by allowing the selection of one of a plurality of impedance matching ratios between the circuit and other elements. The tunable impedance match comprises a microwave impedance transformer with at least a single primary winding, and a plurality of secondary windings, wherein the winding configuration is determined by an electrical switching apparatus allowing the secondary windings to be connected in series, parallel and combinations thereof to provide the required impedance matching. The method allows for both dynamic matching of an integrated semiconductor circuit for increased efficiency, and hence reduced power consumption, and directly matching said circuit to high impedance antennae etc.

摘要： A method and circuit are provided wherein the magnitude of an RF signal provided by RF circuit is used to derive a control set point of the RF circuit via an intermediate controller circuit. This controller circuit having the specific function of providing the actual voltage applied to the control point of the RF circuit, via the use of a charge pump, regulator or combination thereof. In this manner the controller limits the maximum applicable voltage set by the limiting characteristics of the charge pump, voltage regulator, or combination thereof. Such limiting characteristics allow the control of the RF circuit to be stabilized against a variety of external factors such as ambient temperature, battery voltage, circuit aging, amongst other factors in a manner exploiting a minimum of additional electronics thereby providing for such performance enhancements with minimum additional die footprint and power consumption.

摘要： A circuit for providing AM/PM modulation is described. The circuit includes a signal generator, which provides two phase modulated (PM) signals used to form two drive signals which are later combined in a constructive/destructive fashion. The combination of the two phase modulated signals form a signal for driving a load. When the load is driven, the resulting signal is AM/PM modulated.
