Abstract: A clock signal generator, which requires no clock selection pin includes a multiplexer to which external and internal clocks are applied. The external clock is further coupled directly and via an inverting delay to a logic circuit, the output of which controls a switching device connected across a capacitor. The capacitor is coupled to a current source and to a comparator that is coupled to a reference voltage. The comparator output serves as the select control for the multiplexer. The switching device repeatedly discharges the capacitor in response to the external clock signal, but otherwise allows the capacitor to be charged by the current source. The external clock signal is coupled to the output of the multiplexer, as long as the capacitor is repeatedly discharged by the external clock signal at a frequency sufficient to maintain the voltage across the capacitor less than the reference voltage.

Abstract: A power supply switching circuit arrangement is configured to provide a relatively smooth (low noise) power supply switch-over during the transition between active and quiescent modes. Complementary inputs of an operational amplifier are selective coupled to feedback paths to the amplifier and the power supply switching circuit arrangement, so as to bias a switching transistor during system active mode at a value that is just slightly below the turn-on voltage of the transistor. This means that turning on the switching transistor for the purpose of providing quiescent mode powering of the utility device requires only a small transition in control voltage from an active mode nullalmost turned-onnull level.

Abstract: A controller for a multiphase converter including an error amplifier, a gain resistor, a current sense circuit and a gain adjust amplifier. The error amplifier generates an error signal based on an error voltage developed across a feedback resistance. The current sense circuit converts each of multiple sensed load currents into corresponding proportional voltages. The gain adjust amplifier circuit receives the proportional voltages and operates to apply at least one gain adjust voltage to the gain resistor to develop a gain adjust current that is applied through the feedback resistance to adjust gain. In one embodiment, the proportional voltages are time multiplexed or averaged to provide the gain adjust voltage(s). An IC integrating the multiphase converter need only include a single gain pin for coupling to a gain resistor to set gain for each phase.

Abstract: A modified Brokaw cell-based circuit produces a current which varies linearly with temperature. The collector-emitter current flow path of a diode-connected transistor is connected in series with the PTAT current produced by a control transistor. The base of the control transistor receives a control voltage whose value defines a limited range of variation of output current with temperature. The output transistor is coupled to an input port of a current mirror, which mirrors the linear collector current from the output transistor. The current through the output transistor is controlled by a composite of a CTAT base-emitter voltage of the diode-connected transistor and a PTAT voltage across a resistor, so that the output transistor produces an output current having a linear temperature coefficient.

Abstract: The present invention relates to integrated circuits having symmetric inducting devices with a ground shield. In one embodiment, a symmetric inducting device for an integrated circuit comprises a substrate, a main metal layer and a shield. The substrate has a working surface. The main metal layer has at least one pair of current path regions. Each of the current path region pairs is formed in generally a regular polygonal shape that is generally symmetric about a plane of symmetry that is perpendicular to the working surface of the substrate. The shield is patterned into segments that are generally symmetric about the plane of symmetry. Medial portions of at least some segments of the shield are formed generally perpendicular to the plane of symmetry as the medial portions cross the plane of symmetry.

Abstract: A programmably switched, multi-output stage current mirror-based, current-sensing and correction circuit controls the operation of a buck mode DC-DC converter. This correction circuit generates a correction current having a prescribed step-wise temperature-compensating relationship to sensed current. The sensed current is derived from a variable impedance controlled by a sense amplifier coupled via a current feedback resistor to the common output node between a high side power switching device and a low side power switching device of the converter. To program the correction circuit a decoder maps temperature information associated with the low side power switching device and additional programming information into a current mirror control code.
