摘要： A method and apparatus are provided for reducing distortion in a dynamically delayed digital sample stream of an imaging system. The method includes the steps of delta-sigma modulating an input analog signal of the imaging system at a frequency above the Nyquist frequency of the input analog signal to generate a digital sample stream and changing a length of the sample stream to delay a portion of the sample stream while maintaining synchronism between a delta-sigma modulator and a demodulator of the system.

摘要： A symmetric pipelined charge-mode analog to digital converter including a signal-reference CCD channel having a plurality of charge storage stages that are arranged in a serial configuration to carry the signal and reference charges, and a CCD digital channel. A set of two step comparators coupled to the signal-reference channel first senses and stores the signal charge and then senses and compares the reference charge to the signal charge. In the first stage, an initial reference charge is used, and in subsequeant stages, an increment of one half the previous stage increment is added to the reference. In addition, at each stage, a charge increment equal to the previous reference increment is conditionally added to the signal charge and a corresponding bit in the digital channel is conditionally set responsive to the comparator. Thus, if the total signal charge is less than the total reference charge at a stage, the charge increment is added to the signal charge in the signal-reference channel, and a corresponding digital bit charge is zeroed in the digital channel. Conversely, if the total signal charge is larger than the told reference charge at a stage, the charge increment is not added to the signal charge and a corresponding digital bit charge is set to represent a one in the digital channel. One configuration provides a differential symmetric architecture wherein two signal-reference channels simultaneously feed a dual symmetric comparator providing enhanced symmetry thereby reducing threshold and offset sensitivity and susceptibility to environmental factors such as ionizing radiation.
摘要翻译：一种对称流水线充电模式模数转换器，包括具有多个电荷存储级的信号参考CCD通道，该多个电荷存储级以串行配置布置以承载信号和参考电荷，以及CCD数字通道。耦合到信号参考通道的一组两级比较器首先感测并存储信号电荷，然后感测并比较参考电荷与信号电荷。在第一阶段，使用初始参考电荷，并且在辅助级中，将前一级增量的一半的增量添加到引用。此外，在每个阶段，等价于先前参考增量的电荷增量被有条件地加到信号电荷上，并且响应于比较器有条件地设置数字信道中的相应位。因此，如果总信号电荷小于一级的总参考电荷，则将电荷增量添加到信号参考通道中的信号电荷，并且相应的数字位电荷在数字通道中归零。相反，如果总信号电荷大于一级的告知参考电荷，则不向信号电荷添加电荷增量，并且将相应的数字位电荷设置为在数字通道中表示一个。一种配置提供了一种差分对称架构，其中两个信号参考通道同时馈送双对称比较器，提供增强的对称性，从而降低阈值和偏移灵敏度以及对诸如电离辐射的环境因素的敏感性。

摘要： A floating point analog to digital converter having an exponent converter which divides the input signal successively one-half until the divided signal is within the range of a mantissa linear analog to digital converter. The exponent converter also generate a digital exponent representative of the division factor. The resulting divided signal is then digitized by the mantissa analog to digital converter. An output is thereby provided composed of a digital exponent and a digital mantissa. In one embodiment, the floating point converter is a charge mode converter suitable for direct interface to a charge mode device such as a CCD image sensor.

摘要： The high speed data pathway system is used to convey data signals to integrated circuits connected to mother and daughter boards. The integrated circuits include a package and an integrated circuit chip carried by the package. An internal transmission line is carried by the package and coupled to the integrated circuit chip. The package includes both input and output connections for the internal transmission line. A high speed pathway is formed by serially connecting the internal transmission lines with external transmission lines to form a unified transmission medium. Advantageously, the internal transmission lines, external transmission lines and the connection between them have substantially corresponding characteristic impedances.
