Abstract: A method and a system for supplying power to a microcontroller with a single cell. One embodiment of the present invention discloses incorporation of a power supply pump circuit with the microcontroller and their dynamic interaction. The microcontroller sends its power requirements to the power supply pump circuit and in response, the power supply pump circuit controls the operating voltage with optimal efficiency. The dynamic update of power supply pump circuit results in an efficient use of the power supply pump circuit and thus results in a reduction of the number of dry cell batteries to only a single cell. Incorporation of the microcontroller and power supply pump circuit onto a single chip reduces the pin number requirements as well as the space required on the printed circuit board.

Abstract: A multiplexer circuit provided herein includes a plurality of pass devices coupled in parallel between a power supply and a ground supply. According to one embodiment, each pass device may include a first pair of transistors, which is coupled in series between the power supply and the ground supply, and a second pair of transistors, which is coupled to the first pair of transistors for controlling a current passed there through. In general, the second pair of transistors may be configured for increasing the amount of current passed through the first pair of transistors. For example, the second pair of transistors may utilize a bootstrapping effect to increase a pair of control voltages supplied to the gate terminals of the first pair of transistors. The increased control voltages function to over-drive the gate terminals of the first pair of transistors, thereby increasing the amount of current passed there through.

Abstract: A method and apparatus for creating USB peripheral device report descriptors: A short, compressed, report descriptor is stored in a peripheral device. This short report descriptor is transmitted to a USB wireless bridge and combined with templates stored in the bridge to create a USP report descriptor. Power is saved because less time is required to transmit the short report descriptor than would be required to transmit a full USB report descriptor. Hardware is also saved in the peripheral device since less memory is required to store the short report descriptors as compared to storing a full USB report descriptor.

Abstract: An arbiter circuit (100) can include a latch circuit (102) that latches competing input signals (MATCH1 and MATCH2) to generate signals on latch output (110-0 and 110-1).

In addition, filter section (104) can generate output signals (BUSY2 and BUSY1) having one set of values when both inputs are inactive, and a second set of values when latch (102) is in the metastable state.

Abstract: A method for emulating and debugging a microcontroller. In one embodiment, an event thread is executed on an emulator that operates in lock-step with the microcontroller. Event information is sampled at selected points. Trace information is also recorded at the selected points. As such, the event information and trace information are effectively pre-filtered. Accordingly, it is not incumbent on a designer to read and understand the event and trace information and sort out the information that is of interest. Instead, this task is essentially done automatically, helping the designer and reducing the probability of error. Furthermore, because only selected event and trace information is recorded, the resources of the in-circuit emulator system are not taxed.

Abstract: Memory circuits having different configurations of local word line driving circuits (LWLDC) and methods for designing such circuits are provided. The memory circuits include an array of memory cells and a plurality of local word lines each coupled to a different subset of the array of memory cells. The memory circuit further includes a plurality of LWLDC respectively coupled to the plurality of local word lines, a global word line bus coupled to the plurality of LWLDC, and a global word line driving circuit (GWLDC) coupled to the global word line bus. At least one of the plurality of LWLDC may be configured to have a smaller amount of load capacitance than another LWLDC arranged comparatively farther from the GWLDC. In some embodiments, the variance of load capacitance may be induced by a variance of size among the plurality of LWLDC, specifically with reference to different transistor width dimensions.

Abstract: A capacitive sensing system (100) can connect groups of capacitive sensors (112-1 to 112-N) to a common node (106) to detect change in capacitance. States of a set of capacitive sensors (112-1 to 112-N) can thus be scanned faster than approaches that scan such sensors one-by-one. Faster scanning can allow for reduced power consumption in applications that only periodically scan the set of capacitive sensors (112-1 to 112-N).

Abstract: A method and system for cycle slip framing is disclosed. The method includes receiving an asynchronous signal and generating a synchronous pulse after receiving the asynchronous signal. The method further provides that the synchronous pulse be used to affect a bit slip that results in the moving of a character frame in the recovered data of a deserializer. According to one embodiment of the invention, the moving of the character frame is prompted by a single control signal of a clock divider circuit which causes the removal of a single clock cycle of a clock signal supplied to said deserializer.

Where the feedback counter times out first, a constant charge pump current is delivered to the loop filter to achieve a downward frequency direction.
