摘要： Embodiments of the present invention provide a low voltage continuous time common mode feedback (CMFB) module, for low voltage operational amplifiers, providing good linearity, wide bandwidth and low systematic offset. The common mode feedback module includes a controlling module and an initializing module. The controlling module and the initializing module are parallel common mode feedback loops. The controlling module is a main CMFB loop and the initializing module is an auxiliary CMFB loop and both the loops work simultaneously. The controlling module and the initializing module receive a first differential input voltage and a second differential input voltage supplied by differential outputs of a main differential amplifier. Both the CMFB loops are low gain amplifiers in order to provide operation as linear as possible over the entire differential output operating range of the main differential amplifier.

摘要： A memory device that accurately tracks memory operations includes a vertical loopback for tracking a sense clock signal to a row address decoder, and read and write reference bit lines in a reference column that include loopbacks for vertically tracking a selected bit line during read and write operations. Preferably the widths of word lines and a sense line are equal to enable the sense line to horizontally track any selected word line. The memory device also includes tri-state input/output (I/O) latches to latch sense amplifier outputs. A drive circuit of the tri-state I/O latch is disabled when the output is available at the corresponding sense amplifier and enabled when the output is latched by the latch circuit.

摘要： Described are methods and apparatuses, including computer program products for utilizing emergency procedures to determine location information for a Voice Over Internet Protocol (VOIP) device. A wireless access gateway (WAG) determines location information of the VOIP device and stores the location information. A request for a location of the VOIP device from a Mobile Switching Center (MSC) is received by the WAG. The WAG translates the stored location information into a format used by the MSC to receive location information from a Radio Access Network (RAN). The WAG provides the translated location information to the MSC.

摘要： A parallel operation keyboard (POK) which enables a user to provide multiple inputs simultaneously in managing a process control plant. A lock is provided to disable such simultaneous inputs. In an embodiment, multiple groups of keys are provided, with each group of keys being operable independently to modify the parameter value of a corresponding control loop. A network management station (NMS) and a server are designed to provide a suitable interface. In one implementation, each group of keys contains four keys respectively specifying increasing the parameter value, decreasing the parameter value, manual mode (in which the present level of the variable is controlled by the increase/decrease keys) and normal mode (in which the set point, i.e., the desired value, for the variable is controlled).
