摘要： Phase of an output signal is based on comparison of an oscillating signal with an adjustable threshold. Here, adjustment of the threshold results in a corresponding adjustment of the phase of the output signal. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal. In some aspects these phase adjustment techniques may be employed to provide one or more tunable multiphase clocks.

摘要： Frequency of an oscillating signal is temporarily adjusted to adjust frequency and/or phase of an output signal. For example, the frequency of the oscillating signal may be adjusted for a very short period of time to adjust the phase of the output signal. In addition, the frequency of the oscillating signal may be temporarily adjusted in a repeated manner to adjust the effective frequency of the output signal. In some aspects the frequency of the oscillating signal is adjusted by reconfiguration of reactive circuits associated with an oscillator circuit.

摘要： Frequency and phase of an output signal is adjusted to track an input signal. A control signal is adjusted to control a frequency of an oscillating signal from which the output signal is derived. In some aspects the frequency of the oscillating signal is adjusted by reconfiguration of reactive circuits coupled to an oscillator circuit. Phase of the output signal may be adjusted based on comparison of the oscillating signal with an adjustable threshold. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal.

摘要： A matched filter and peak detector identify peaks of a received signal. The peak detector may detect peaks during a fixed or adjustable time window. The peaks may be used as a preliminary decision (e.g., soft decision) for subsequent receiver decoding operations. The detector may be used to detect high bandwidth signals such as ultra-wide band signal pulses yet consume relatively minimal power.

摘要： A light fixture includes a ballast and a plurality of lamps connected to the ballast in parallel. The ballast provides an output signal to the plurality of lamps as a function of a 1st steady state condition. When the ballast senses an end-of-life condition for a lamp of the plurality of lamps, the ballast increases the frequency of the output signal provided to the plurality of lamps until the lamp ceases to conduct current. When the lamp ceases to conduct current, the ballast decreases the frequency of the output signal to a frequency determined as a function of a 2nd steady state condition different from the 1st steady state condition. A total current of the 2nd steady state condition is proportional to a total current of the 1st steady state condition as a function of the number of lamps exhibiting an end-of-life condition.

摘要： A ballast includes a rectifier, DC to DC converter, a dimming sensor, and a light source driver circuit. The rectifier provides rectified power from an AC power source modified by a chopper dimmer. The converter includes a boost inductor having a primary winding and a detection winding. The converter receives the rectified power from the rectifier and provides a DC power rail. The dimming sensor monitors a voltage of the detection winding of the boost inductor and provides a dimming signal as a function of the monitored voltage. The light source driver circuit receives the dimming signal, receives the DC power rail, and provides power from the DC power rail to the light source as a function of the dimming signal. An amount of power provided to the light source by the light source driver circuit corresponds to a dimming level indicated by the dimming signal.
