摘要： A device (200) includes a circuit (202) and a driver stage (204) therefor. The circuit includes two sub-circuits (231 and 232). The driver stage includes switcher logic (206) that produces signals that control switching on and off of the sub-circuits. The switcher logic also produces other signals in advance of the signals that control the switching of the sub-circuits. The driver stage includes delay compensations circuits (221 and 222), coupled to the switcher logic and to the circuit, that produce timing signals for the switcher logic. The timing signals are closely aligned with moments that a changing voltage at a node between the sub-circuits passes through threshold voltages. The timing signals compensate for all delays of signals through the device such that a period that both sub-circuits are off is minimized, while ensuring that both sub-circuits are not on at a same time.

摘要： A transceiver suitable for interfacing a logic device to a shared bus includes a transmit node that receives an input signal from the logic device and an I/O node, that is coupled to the shared bus. The transceiver may be designed for use with a shared-bus, single master, multiple slave architecture, e.g., a Local Interconnect Network (LIN). In a LIN compliant implementation, the transceiver may be suitable for use in at least some types of automobiles and other motorized vehicles. Control logic coupled to the transmit node may assert a current driver enable signal in response to detecting an assertion of the input signal. A current driver of the transceiver is configured to draw a time varying driver current from the shared bus node after detecting an assertion of the current driver enable signal. The driver current may cause a sinusoidal transition of the shared bus voltage.

摘要： A voltage reference module of an integrated circuit device includes a current source to apply a current to a set of voltage cells, thereby generating a voltage drop across each cell. The voltage cells are configured such that the individual voltage drop associated with each cell in response to the application of the current is relatively stable over a temperature range. The voltage reference module generates a voltage based on the voltage drops across the voltage cells, and therefore the generated voltage is also stable over the temperature range. Bypass switches can be connected across each voltage cell whereby the switches can be individually opened and closed to include or exclude cells in generation of the reference voltage. In an embodiment, the switches are set during a trimming process for the integrated circuit device so that the voltage reference module provides a specified voltage.

摘要： A testing circuit in an integrated circuit indirectly measures a voltage at a node of other circuitry in the integrated circuit. The testing circuit includes a transistor having a control electrode, a first conducting electrode coupled to a first pad, a second conducting electrode coupled to a terminal of a power supply, and one or more switches for selectively coupling the control electrode to one of the node and a second pad. A method includes determining a relationship between drain current and gate voltage of the transistor when the control electrode is coupled to the second pad. A voltage at the node is determined by relating the current through the first conducting electrode of the transistor when control electrode is coupled to the node.

摘要： A touch sensing interface (101) includes a noise touch sensing circuit (110) that utilizes electromagnetic (EM) noise in a touch panel (102) to determine whether a pad of the touch panel is touched, such as by a finger of a user. The noise touch sensing circuit detects noise in a first pad (104) and in a second pad (105) of the touch panel, compares power of the noise in the first pad to power of noise in the second pad, and outputs a signal (132) indicative of the first pad being touched when power of noise in the first pad exceeds power of noise in the second pad by a pre-selected amount. The touch sensing interface may include a capacitive touch sensing circuit (120) and a controller (130) that selectively actuates the noise touch sensing circuit and the capacitive touch sensing circuit.
