摘要： A current mode switching converter includes a transistor switch, an inductor configured to conduct a ramping inductor current as the transistor switch is turned on and off at a particular duty cycle, and an inductor current sensor generating a current sense signal. The current sense signal has an up-slope portion and a down-slope portion. A separate ramp generator generates a ramp voltage for each switching cycle. A slope compensation circuit compensates the ramp voltage, depending on the duty cycle and other factors, to create a compensated ramp voltage. The compensated ramp voltage is then summed with the current sense signal to create a compensated current sense signal for a comparator. The slope compensation circuit forces the compensated current sense signal to have an up-slope greater than an absolute value of its down-slope at least for duty cycles greater than 50% to rapidly dampen perturbations in the duty cycle.

摘要： A battery system monitor includes cell measurement circuits (CMCs) that each measure a voltage at or current through a pair of terminals of a respective associated battery module from among a plurality of plurality of battery modules in a battery system. Wireless communication transceivers (WCTs), each associated with a different CMC, transmit voltage or current measurement information of the associated CMC across a wireless communication link. A controller receives the voltage or current measurement information from the wireless communication transceivers for monitoring the state of operation of the battery system. Battery system monitoring is improved through synchronization of clocks in different CMCs or WCTs to enable synchronous sampling of multiple battery modules, through systems for determining relative positions of battery modules in a series coupling of battery modules between terminals of the battery system, and through improvements to the reliability of wireless communication.

摘要： A testing procedure may determine whether a monolithic voltage reference device meets a temperature drift specification. A first non-room temperature output voltage of the monolithic voltage reference device may be measured while the monolithic voltage reference device is at a first non-room temperature which is substantially different than room temperature. First non-room temperature information may be stored in a memory within the monolithic voltage reference device which is a function of the first non-room temperature output voltage. A second non-room temperature output voltage of the monolithic voltage reference device may be measured while the monolithic voltage reference device is at a second non-room temperature which is substantially different than the room temperature and the first non-room temperature. Second non-room temperature information may be stored in the memory without destroying the first non-room temperature information which is a function of the second non-room temperature output voltage. A determination may be made whether the monolithic voltage reference device meets the temperature drift specification based on a computation that is a function of both the first non-room temperature information and the second non-room temperature information.

摘要： An apparatus and method for event synchronization. One or more devices that have a plurality of events to be carried out in a scheduled order in time are connected to a single shared time position clock (TPCLK). There are one or more sequencing controllers coupled with the one or more devices and configured to control the timing of high and low states of the shared TPCLK in accordance with the scheduled order. The synchronization among the plurality of events in the scheduled order is achieved based on the high and low states of the shared TPCLK and such synchronization of the plurality of events in the scheduled order is operated without the presence of master and slave devices.
