Abstract

We have designed and tested energy-efficient single flux quantum (eSFQ) circuits for use in practical circuits. The first circuit is a 184-bit shift register for acquisition memory to store short transient events. The second circuit is a 16-bit deserializer integrated with an analog-to-digital converter modulator. The deserializer converts a high speed oversampling delta modulator 1-bit data stream into 16 parallel digital outputs at 1/16 of input data rate. In this work, we report preliminary functional and high-speed operation of some of these eSFQ circuits including their margins of operation at different clock speeds, maximum operation frequencies, and power dissipation.
实用eSFQ电路的操作
我们设计并测试了节能的单通量量子(eSFQ)电路,用于实际电路。第一个电路是一个184位移位寄存器,用于存储短暂瞬态事件的获取存储器。第二个电路是一个集成了模数转换调制器的16位反序列化器。反序列化器以输入数据率的1/16将高速过采样增量调制器1位数据流转换为16个并行数字输出。在这项工作中,我们报告了一些eSFQ电路的初步功能和高速运行,包括它们在不同时钟速度下的工作余量,最大工作频率和功耗。
