    • An analog-to-digital converter (ADC) (15) provides digital error correction. Parallel ADC stages are synchronously clocked to convert an analog input signal (A IN) into digital words; at least one of the digital outputs (D OUT) is encoded according to an error correction code. Decision logic circuitry (24) decodes a code word comprised of the concatenation of the digital outputs from the parallel stages, to derive a digital output from which the digital output word corresponding to the analog input signal can be derived. The decision logic circuitry (24) can provide an error signal used to correct the state of one or more bits of the digital output from one of the ADC stages, for the case of a systematic code; alternatively, the decision logic circuitry can directly decode the code word to provide the digital output. The architecture may be applied to stages in a pipelined ADC.
    • 模数转换器(ADC)(15)提供数字误差校正。 并行ADC级同步时钟将模拟输入信号(A IN)转换为数字字; 根据纠错码对至少一个数字输出(D OUT)进行编码。 判定逻辑电路(24)对包括来自并行级的数字输出级联的码字进行解码,以导出数字输出,从该数字输出可导出对应于模拟输入信号的数字输出字。 对于系统码的情况,判定逻辑电路(24)可以提供用于校正来自ADC级之一的数字输出的一个或多个比特的状态的误差信号; 或者,决策逻辑电路可以直接解码码字以提供数字输出。 该架构可能适用于流水线ADC中的阶段。

    • A first multiplexer (216-1) is coupled to a first input terminal (IΝΡ1/ΙΝΡ2) and a second multiplexer (216-2) is coupled to a second input terminal (IΝΜ1/ΙΝΜ2) of a folded cascode differential amplifier (210) which includes transistors (Q1 through Q4) and current sources (222-228). Switching between differential input signals (INP1/INM1) and (INP2/INM2) is controlled through a select signal SELECT provided by a controller (214). A reset mechanism includes a switch (Q5) coupled between output terminals (OUTP, OUTM) of amplifier (210) and controlled by a pulse generator (XOR gate 218 and delay circuit 220). On a rising or falling edge of the select signal SELECT, a pulse is provided to activate the switch (Q5) so as to briefly short the output terminals (OUTP, OUTM). This avoids glitching and results in faster settling times.

    • A tool set (B) with upper and lower tools (12, 13) movable towards and away from each other (arrow 8), and mounted on supports (5, 3) which are mounted on slides (9) for movement perpendicular to the tool movement (8). A locating pin (48) is mounted on the lower tool (13), which, when raised to its operational position, engages a location aperture in a continuously moving strip workpiece, so causing the tools (12, 13) and supports (5, 3) to move along the slides (9), at the same time the tool set (B) is activated to press the workpiece, the press operation being accurately located with respect to the location aperture. The apparatus can also include another tool set (A), which can be used to punch the location apertures, and apparatus (44, 45, 46) which measures feeding of the strip and can be used to control the tool sets (A, B) to form products of predetermined lengths.
