  • Publication number: 20070034608
    Abstract: There are described various methods and circuits for trimming the parameter value of a thermally mutable electrical component in two directions. A sequence of heat pulses is selected as a function of thermal history using an adaptive trimming algorithm, where parameters of the sequence of heat pulses are based on a resulting impact of previous heating pulses. Direction of trimming, trimming increment, and remaining trimming distance can all be used to determine the parameters of succeeding heat pulses, wherein the parameters of the pulses can be, for example, amplitude, duration, and time interval between pulses.

  • Publication number: 20070013389
    Abstract: Electro-thermal trimming of thermally-trimmable resistors is used to trim one or more of the plurality of resistors in or associated with an analog electric circuit. The TCR of each of a subset of a plurality of electro-thermally-trimmable resistors can be trimmed independently from the resistance in order to adjust the output parameter of an analog electric circuit without changing other parameters that would be affected by a change in resistance.

  • Publication number: 20060279349
    Abstract: There is described methods and circuits for trimming a temperature coefficient of change of a parameter of at least one electrical component while maintaining a substantially constant parameter value, the method comprising applying a heating cycle to trim said parameter value away from a target parameter value and back to said target parameter value, whereby the temperature coefficient of change is modified after applying said heating cycle.

  • Publication number: 20040101153
    Abstract: This invention addresses a fundamental weakness in currently common microphones, and their applications in feedback for audio speaker systems. This limitation stems from the fundamental difficulties of typical membrane-type microphones in the frequency range 1-100 Hz. The self-noise of membrane-type microphones increases in this range approximately as 1/f, and membrane-type microphones are sensitive to parasitic inertial vibrations, which are usually very important in this frequency range. The removal of these limitations enables the use of such a sensor (APV sensor) for effective feedback in audio speakers, dramatically improving performance in the low-frequency range of 10-100 Hz. Without feedback, typical audio speakers suffer severe attenuation and/or distortion in this range.
