20090079497	PHASE TUNING TECHNIQUES - A differential frequency divider includes first and second input terminals each configured to receive a differential input signal. The divider also includes a first output terminal configured to produce a first output signal and a second output terminal configured to produce a second output signal. The divider further includes a third input terminal coupled to the first output terminal and a fourth input terminal coupled to the second output terminal. In addition, the divider includes a first variable current source. Altering a current of the first variable current source causes a change in the phase difference between a first output signal of the first output terminal and a second output signal of the second output terminal.	03-26-2009

20090085622	PHASE-LOCKED LOOP START-UP TECHNIQUES - Implementations feature systems and techniques for phase-locked loops (PLLs). In some aspects, implementations feature a system that has a PLL circuit including an oscillator and programmable reference frequency divider circuit or a programmable feedback frequency divider circuit. The PLL includes a control circuit to reduce a time required for a PLL settling time by programming a division value into the programmable reference frequency divider circuit and/or the programmable feedback frequency divider circuit to target the oscillator to operate outside of a system operating frequency range of the oscillator during start-up of PLL operations. The control circuit can program another division value into the programmable reference frequency divider circuit and/or the programmable feedback frequency divider circuit after stabilization of the variable oscillator.	04-02-2009
20090085789	Analog To Digital Converter - An ADC, such as a CT SD-ADC, includes a clock generation circuit that produces charging and discharging clock signals such that a settling time for an integrator in the ADC is increased. The clock signals may control a feedback SD-DAC in the CT SD-ADC. The clock signals also may be asymmetric and/or may result in the settling time of the integrator being greater than half the system clock.	04-02-2009

20090088124	Radio Frequency Receiver Architecture - A receiver includes a common-gate low noise amplifier (LNA) configured to receive an RF input signal and produce an amplified RF signal. A down-converting passive mixer is configured to mix the amplified received RF input signal with a local oscillator signal generated by a local oscillator to generate a down-converted amplified signal. An amplifier is configured to amplify the down-converted signal and has an input impedances in on the order of ohms. Only a single LNA may be required to receive RF inputs in all frequency bands of a multi-band communication standard.	04-02-2009
20100329157	Even-Order Harmonics Calibration - Circuits and methods for a differential circuit involve having one of more pairs of differential transistors with back-gate terminals, where each of the back-gate terminals is biased by a tunable back-gate voltage to compensate for circuit mismatches in the differential circuit and reduce or eliminate even-order harmonics in the output signal. A compensation circuit can be configured to receive data relating to the differential output signal of the differential circuit, and to supply one or more back-gate voltages to the back-gate terminals of the differential transistors to adjust threshold voltages of the differential transistors and suppress even-order harmonics in the differential output signal of the differential circuit.	12-30-2010

20090028239	MOVING PICTURE ENCODING METHOD, MOVING PICTURE DECODING METHOD AND APPARATUSES USING THE METHODS - The moving picture encoding method of the present invention is for orthogonally transforming pixels which constitute a block into coefficients indicating frequencies, quantizing the coefficients, and encoding the quantized coefficients. The method includes: selecting quantized coefficients belonging to a subset of a block, from the block of frequency coefficients which are either the coefficients prior to quantization or the quantized coefficients; and altering the arrangement of the subset in the block. Here, the arrangement of the subset is altered in relation to at least one of the following (i) to (v): (i) the completion of encoding a picture; (ii) the completion of encoding a predetermined number of blocks; (iii) content of a current picture to be encoded; (iv) the position of a block in a picture; and (v) a comparison between each frequency coefficient and a threshold.	01-29-2009

20090297483	Adenovirus vectors specific for cells expressing androgen receptor and methods of use thereof - Replication-competent adenovirus vectors specific for cells which allow a probasin transcriptional response element (PB-TRE) to function, such as cells which express the androgen receptor (AR), and methods of use of such viruses are provided. These viruses comprise an adenoviral gene under control of a transcriptional regulatory portion of a PB-TRE, which is in turn dependent upon AR expression. The gene can be, for example, a gene required for viral replication or the adenovirus death protein gene (ADP). The viruses can also comprise at least one additional adenoviral gene under control of at least one additional prostate-specific transcriptional response element, such as that controlling prostate-specific antigen expression (PSA-TRE). Thus, virus replication can be restricted to target cells exhibiting prostate-specific gene expression, particularly prostate carcinoma cells. An adenovirus of the present invention can further comprise a heterologous gene such as a reporter under transcriptional control of a PB-TRE. The adenovirus vectors can be used to detect and monitor samples for the presence of prostate cells as well as to selectively kill malignant cells producing prostate-specific gene products.	12-03-2009
