  • Patent number: 8134401
    Abstract: The disclosed systems and methods of low offset switched capacitor comparator reduce settling errors. The system operates in two major phases. During a first phase, the input voltage is sampled on the input capacitors and a differential amplifier is configured in a unity gain configuration to sample the amplifier offset. During the second phase, the input voltage difference is amplified at the output of the comparator. The amplifier transient sampling error is reduced by shorting the outputs of the differential amplifier for a shorting period at the start of the second phase. A clocked comparator at the output of the differential amplifier provides a fast comparison using internal positive feedback. The differential amplifier should have developed sufficient differential output voltage to overcome the offset of the clocked comparator.

  • Patent number: 8111731
    Abstract: A method of transmitting signals in a communication system over at least two time periods including generating a base signal comprising of at least two samples in each time period, selecting a scrambling sequence of length equal to or greater than the number of time periods, scaling all samples in said signal in a time period with one element of said scrambling sequence and transmitting the scaled signal in said time period. Different elements of the scrambling sequence are used to scale the base signal in different time periods. The signal in each time period is obtained by scaling a base signal. The scrambling sequence is preferably a pseudo-random sequence. The step of scaling all samples in said signal in a time period consists of multiplying all samples of said signal with an element of said scrambling sequence.

    Abstract: A system and method of aligning a micromirror array to the micromirror package and the micromirror package to a display system. One embodiment provides a method of forming and utilizing a package that exposes regions of an alignment reference plane. The device within the package is mounted on the reference plane such that the exposed regions allow precise alignment with the device in a direction perpendicular to the reference plane. Alignment surfaces formed in a display system or other system contact the reference plane at the exposed regions to position the packaged device relative to other components of the system. One embodiment of the package 400 taught has laminated layers forming the package substrate 402 and providing a precision reference plane 416 relative to the position of the micromirror device 404. The package may be formed by laminating several layers of material in sheets to form several package substrates simultaneously.

  • Patent number: 7176821
    Abstract: A digital sigma-delta modulator requiring minimal die area and dissipating minimal power is formed with a plurality of integration stages coupled in tandem between an input node and an output node. The bit width of signals in the integration stages is progressively reduced from the first to the last integration stage without compromising modulator accuracy. A quantizer between the last integration stage and the output node provides the final reduction of signal bit width. The gain of the modulator feedforward and feedback paths are integer powers of two to further simplify the digital computation. In an exemplary implementation, three integration stages to form a third-order modulator are coupled in tandem between the input node and the output node. The gains of feedback and feedforward paths in one preferred embodiment are unity, and in some embodiments, one feedforward path has gain of 0.5.

  • Publication number: 20050104760
    Abstract: To apply a desired voltage at a node driving a load impedance, a voltage source providing the desired voltage is connected to the node. In addition, a current source supplying an amount of current that would be drawn by the impedance if the voltage source alone were connected across the impedance. As a result, the voltage source may be freed substantially from supplying current, which may be advantageously used in several situations. For example, the approach can be used to connect a voltage source directly to a high load without potentially requiring a buffer between the voltage source and the node. Alternatively, the approach can be used to apply the same desired voltage at each of multiple nodes connected in series using the same voltage source without being affected by the routing resistance generally present between each pair of the nodes.

  • Patent number: 5892450
    Abstract: The invention relates to a circuit arrangement for testing the operation of a current monitoring circuit for a power transistor. The power transistor consists of several single transistors of the same size connected in parallel, through which a fraction of the total current supplied to the power transistor flows. A monitoring signal proportional to the current flowing through one of the single transistors, is supplied to the current monitoring circuit, which generates an alarm signal when this monitoring signal exceeds a specified threshold value. The single transistors are divided into a group containing a small number of single transistors (T.sub.1.1 -T.sub.1.9) connected in parallel and a group with a larger number of single transistors (T.sub.2.1,1 -T.sub.2.2,9) connected in parallel, which can be driven independently of each other, where the single transistor (T.sub.S) supplying the monitoring signal belongs to the smaller group.
