摘要： A circuit and method are provided herein for monitoring the status of a clock signal. In general, the method may include supplying a pair of clock signals to a clock monitor circuit, which is configured for monitoring a status of one clock signal relative to the other. The status indicates whether the frequency of the one clock signal is faster, slower or substantially equal to the frequency of the other clock signal. Once determined, the status may be stored as a bit pattern within a status register, which is operatively coupled to the clock monitor circuit. This enables the status to be read by detecting a logic state of one or more bits within the status register.

摘要： A system and method are provided herein for monitoring the integrity of a power supply by monitoring a level of the power supply voltage supplied to one or more system components. The method, as described herein, includes setting a bit in a status register after the power supply level reaches a threshold level, and monitoring a state of the bit to determine if the power supply level has dropped below the threshold level. For example, the method may determine that the power supply level has dropped below the threshold level if the state of the bit changes from a set bit to a cleared bit. In addition, the system and method described herein may be used for detecting the occurrence of a power abnormality by providing additional resources/information about a power related event.

摘要： Circuits and methods are provided herein for monitoring the integrity of a power supply, the circuits and methods providing additional resources/information for diagnosing a cause behind a reset signal, and in some cases, a reason behind a power failure. A first method described herein provides exemplary steps for monitoring a level of a power supply voltage supplied to one or more system components. A second method describes exemplary steps for monitoring an electrical connection between the power supply (or ground supply) and one or more supply pins. Each of the methods involves monitoring a state of one or more bits stored, e.g., within a status register. The methods may be used separately, or in conjunction with one another, for detecting the occurrence of a power abnormality.

摘要： The present invention provides a means for efficiently and securely collecting, storing, and sharing all types of personal, electronic information from, for and between individuals and business users using software that runs on multiple personal, business and cloud computing systems. The information of a primary user is stored in an encrypted relational database which associates the private data with private data fields needed by secondary users or various business users. Each entity is assigned one unique user identity to ensure consistency in data privacy and sharing. Attributes for data groups exist to define the secondary users and business users who the primary user has authorized for access to or master sourcing of certified data. Change lists, including conditions for implementation, are created to facilitate management, scheduling and distribution of changes. Collection, storage, and distribution of personal data is assisted by robotic process automation algorithms.

摘要： A buffer circuit, system, and method are provided. The buffer circuit includes a control circuit coupled to an output of the buffer, or possibly to an output of the first stage of a buffer. A pre-charge circuit is also provided coupled to bias an input of the control circuit to a voltage value approximately near a threshold voltage of the control circuit. The pre-charge bias amount is slightly less than the amount needed to place the control circuit in a high current conduction state. A coupling circuit is thereafter used and adapted to couple an input voltage applied to the buffer circuit to the input of the control circuit. This causes the control circuit to enter the high current conduction state. Depending on the input impedance of the coupling circuit, by pre-charging the coupling circuit input, less time is needed to cause the coupling circuit to enter and thereafter leave a high current conduction state. Therefore, by pre-charging the coupling circuit, output transitions from the buffer circuit can be accelerated and propagation delay reduced. The pre-charge circuit and the control circuit operate on one or more stages of a single or multi-stage buffer, operate on single-ended or differential/complementary input/output, and operate to speed up either the rising, falling, or both edges transitions at the output of the buffer.

摘要翻译： 提供了缓冲电路，系统和方法。 缓冲电路包括耦合到缓冲器的输出或可能地连接到缓冲器的第一级的输出的控制电路。 还提供预充电电路，其被耦合以将控制电路的输入偏置到大约接近控制电路的阈值电压的电压值。 预充电偏置量略小于将控制电路置于高电流导通状态所需的量。 之后使用耦合电路并且将耦合电路耦合到施加到缓冲电路的输入电压到控制电路的输入端。 这使得控制电路进入高电流导通状态。 根据耦合电路的输入阻抗，通过对耦合电路输入进行预充电，需要更少的时间来使耦合电路进入并且之后留下高电流导通状态。 因此，通过对耦合电路进行预充电，可以加速来自缓冲电路的输出转换，并减少传播延迟。 预充电电路和控制电路在单级或多级缓冲器的一个或多个级上工作，在单端或差分/互补输入/输出上工作，并且操作以加速上升，下降或两者 边缘在缓冲区的输出处转变。

摘要： An analog spread spectrum signal generation circuit. A clock generator generates a periodic signal. A plurality of switchable analog loading elements each load the periodic signal by a respective load to vary propagation delay of the periodic signal to an output node. A decoder controls the plurality of switchable analog loading elements. A counter coupled to drive the decoder causes the output node to generate a periodic spread spectrum signal with modulated phase. In one embodiment, the periodic spread spectrum signal with modulated phase is used for reducing radiated electromagnetic interference and downstream phase-locked loop tracking error.

摘要： Embodiments of the present invention provide for generating a sampled differential pattern signal with reduced jitter. In one embodiment of the present invention, a seed frequency generator provides a differential seed frequency signal. The differential seed frequency signal is converted to a single ended seed frequency signal by a differential-to-single ended converter. The pattern generation logic utilizes the single ended seed frequency signal to generate single ended pattern signals. Single ended-to-differential samplers then generate a sampled differential pattern signal by sampling the single ended pattern signal according to the differential seed frequency signal.

Mobile position recording devices including for example global navigation satellite system (GNSS) receivers, accelerometers, and magnetic orientation circuits plus monitoring software and means for data storage are provided to individuals who then travel to various destinations on foot and/or by mechanically assisted means. The position recording devices record route and location information with sufficient detail to provide a navigable map of the routes taken. The routes of various individuals are combined to provide an area wide map of navigable routes and repeated routes are identified and averaged over time to provide increased route detail and accuracy. The location and route data are separated into public and private data and the identity of the service recipient is protected from disclosure to service providers.
