Abstract: A bias filtering module with at least two capacitive levels satisfies both a settle time requirement and a filtering requirement using a voltage dependent filter module whose capacitance is a function of a voltage potential on the filtering circuitry output terminal. The final capacitance level is approximately three times larger than the initial capacitance level.

In an alternate embodiment, a selectable first group of capacitors are switched into connection within the bias filtering module as a second group of capacitors approximately reach a fully charged state within a specified settle time to provide improved filtering.

Abstract: Method and system for data-rate control by randomized bit-puncturing in communication systems. An encoder encodes at least one information bit thereby generating a group of encoded bits or an encoded frame. The encoder may be any type of encoder including a turbo encoder, an LDPC (Low Density Parity Check) encoder, a RS (Reed-Solomon) encoder, or other type of encoder. Any sub-portion of an encoded frame generated by such an encoder can be viewed as being a group of encoded bits. If the encoded frame is sub-divided into multiple groups of bits, each group can under processing in accordance with the means presented herein to effectuate rate matching. Based on a number of bits to be punctured from the group or frame generated by the encoder, a set of pointers and random-generated displacements is used to generate addresses for bits in the group or frame to be transmitted or punctured.

Abstract: A system and method for regulating power consumption within an integrated circuit (IC) with a modular design. The IC is designed so that any one distinct functional module within the IC utilizes only transistors with a substantially same or similar critical voltage level, which may for example be the threshold voltage of the transistors. Consequently, the supply voltage delivered to each functional modules can be lowered to the minimum voltage necessary to enable the transistors within the module to operate. Similarly, modules within the IC may be designed with transistors which share a common value for a substrate bias voltage or a clock speed, or with a combination of common values for several electrical factors. In this way, it is possible to reduce power consumption by fine-tuning the voltages supplied to (or clock speeds driving) specific modules, in a way which is custom-tuned to each module.

Abstract: A GNSS enabled mobile device receives GNSS signals from visible GNSS satellites. Broadcast ephemeris is extracted from the received GNSS signals for generating ephemeris extension (future ephemeris) in the next several days for each of the visible GNSS satellites. The GNSS enabled mobile device uses the generated future ephemeris to determine a position fix even without fresh broadcast ephemeris completely received from the visible GNSS satellites. The generation of future ephemeris is scheduled according to the age of available ephemeris extensions and/or the time of visibility. Available ephemeris such as extracted broadcast ephemeris are integrated into an orbit model using the multi-step numerical integration methods and propagated to generate future ephemeris. The generated future ephemeris is reformatted into a desired orbit model and/or format of the GNSS enabled mobile device.
