    Abstract: A method for statistically calibrating a digital-to-analog converter with an electronic test system. The digital-to-analog converter is excited with two state signals at each input bit which together represent a single signal with uniform amplitude probability with respect to time, and wherein each excitation signal is orthogonal with respect to all other excitation signals. The output of the digital-to-analogconverter is detected by an analog-to-digital converter which has been calibrated by premeasured weighting coefficients with respect to two-state orthogonal signals. The digital time domain output signals are then mapped into a transform domain to obtain weighting coefficients of each bit of the output response. Finally the transform domain weighting coefficients are weighted by the reciprocal of the premeasured weighting coefficients to obtain the unbiased weight of each bit of the digital-to-analog converter under test. A preferred set of excitation signals is a set of Walsh function signals representing the digital equivalent of a linear ramp function.

    Abstract: Some general aspects of the invention relate to a circuit and to a method for analog computation, for example, using switched capacitor integrated circuits. In some examples, a circuit includes a first group of capacitors and a second group of capacitors that may store charges during circuit operation. The first and/or the second group of capacitors may include multiple disjoint subsets of capacitors. An input circuit is provided for receiving a set of input signals and for inducing a charge on each of some or all capacitors in the first group of capacitors according to a corresponding input signal. Switches, for example, transistors controlled by a sequence of clock signals, are used to couple different sets of capacitors. Different configurations of the switches are used to form different sets of the capacitors among which charge can redistribute.

    Abstract: A system for efficient implementation of transforms. The implementation by flows of particles, and summation by a conservation low offers savings. In particular for an electronic implementation, a current mode implementation is described, by which replicators, sign changers are implemented by current mirrors and summation is performed in a node by Kirchoffnulls law. The transform implementation is efficient for on-chip compression avoiding the need to convert to digital all signals from a sensing array. It is also an efficient implementation for direct control of an emitting array, such as a display which can be directly controlled with outputs from a transform block performing decompression.

    Abstract: A permutation memory comprises an input control means for decoding, having plurality L of inputs for an L-bit binary number, and a plurality 2.sup.L of outputs. Means are connected to the decoding means, for initiating the read-in of the L-bit number. Means are provided for applying an input signal. A first plurality of 2.sup.L of normally open switching means are connected to the 2.sup.L outputs of the decoding means and to the signal applying means. A plurality of 2.sup.L of means are connected to the switching means, for storing a charge when a specific switching means, connected to a corresponding charge storing means, is in a closed condition. A second plurality 2.sup.L of switching means are connected to the first plurality of switching means and to the charge storing means. An output control means, connected to the second plurality of switching means, reads out the states of the 2.sup.L charge-storing means, as to the amount of charge in each. Means are connected to the read-out means, for initiating the read-out.
