摘要： A spur-free sigma delta modulator analog-to-digital converter for converting an analog input signal to a digital output signal is provided. A race Josephson junction is provided between the pulse generator and the integrating inductor. The race Josephson junction emits a voltage pulse in response to every sampling pulse. This voltage pulse kills any retained persisting current in the integrating inductor. By adding the race Josephson junction, nonlinearities in the converter are eliminated.A multiple flux quanta feedback generator for creating a multiple digital pulse feedback in response to an input signal is provided. A quantizer connected to the input inductor produces a pulse when the current produced by the input inductor exceeds a predetermined amount. A splitter is connected to the quantizer for producing output pulses. In order to produce 2.sup.n output pulses, 2.sup.n -1 splitters are required. Each of the splitters produces two output pulses in response to a single pulse produced by the quantizer. Each of the 2.sup.n output pulses drives one of 2.sup.n feedback pulse generators. Each of the feedback pulse generators is connected to one of the output pulses to produce 2.sup.n +1 quanta feedback which is fed back to the input inductor.
摘要翻译：提供了一种用于将模拟输入信号转换为数字输出信号的无差动Σ-Δ调制器模拟 - 数字转换器。在脉冲发生器和积分电感之间提供一个比赛约瑟夫逊结。比赛约瑟夫逊结响应于每个采样脉冲发出电压脉冲。该电压脉冲杀死积分电感器中的任何保留的持续电流。通过添加比赛约瑟夫逊结，消除了转换器中的非线性。提供了用于响应于输入信号产生多个数字脉冲反馈的多通量量子反馈发生器。当输入电感器产生的电流超过预定量时，连接到输入电感器的量化器产生脉冲。分路器连接到量化器以产生输出脉冲。为了产生2n个输出脉冲，需要2n-1个分离器。每个分离器响应于由量化器产生的单个脉冲产生两个输出脉冲。 2n个输出脉冲中的每一个驱动2n个反馈脉冲发生器中的一个。每个反馈脉冲发生器连接到一个输出脉冲以产生被反馈到输入电感器的2n + 1个量子反馈。

摘要： A serial multiplier for multiplying two n-bit numbers is provided in which a shift register having a total of n destructive read out cells contains a separate bit of a first multiplicand in each cell. A string of (2n-1) non-destructive read out cells is provided to receive the second multiplicand. Each of the first n cells of the string of non-destructive readout cells contain a separate bit of the second multiplicand. Each bit of the first multiplicand is serially multiplied with the series of bits of said second multiplicand. After each such multiplication, each bit of the second multiplicand is moved to the next adjacent cell. The partial product of the multiplication is stored in a string of 2n T flip-flop cells. Each of the T flip-flop cells has a carry path to the next adjacent T flip-flop cell. Timing means are provided to regulate and initiate the multiplication.

摘要： A switch for controlling the throughput of a signal between a pair of input channels and a pair of output channels is provided which receives an input signal from each of the pair of input channels. The switch transmits an output signal to each of the pair of output channels. Four line channels are provided within the switch. Each of the four line channels connects one of the pair of input channels and one of the pair of output channels. Four line channel switches are also provided, one line channel switch provided on each of the line channels. Each of the four line channel switches is controlled by a signal to open or close the four line channels.
