“…An example of a DFF-based PRNG is presented in [43]. In that implementation, input pulses to the DFF-based shift register are routed to the data input "D-line" and the clock input to the input "C-line".…”

This paper presents a superconducting, magnetically-coupled, shuttle-flux shift register (SF-SR) that stores single flux quantum (SFQ) pulses. This shift register has a DC bias operating margin of ±34% at 10 GHz, with a power dissipation of 3.6µW and 38% fewer Josephson junctions (JJs) when scaled up to multiple stages compared to a data flip-flop (DFF) based shift register. The clock input is inductively coupled and is independent from the data input. We then present three applications for our SF-SR. In the first application, we add two non-destructive readout (NDRO) cells to construct a buffer that temporarily stores the temporal information of a series of race logic (RL) pulses. The second application is a pseudo-random number generator based on a linear function shift register (LFSR). The third application is N parallel SF-SRs that can act similar to a deserializer or instead can emulate a single SF-SR of N times higher clock frequency. These three applications motivate deep shift registers with many shifting intervals, which our SF-SR can implement with fewer JJs and lower power consumption compared to DFF-based shift registers.

Noise has been studied extensively in the literature because noise reduction is one of the major goals. A more compelling reason for the study of noise is its potential application in real life. These applications encompass biomedical engineering, electronic circuits, communication systems, cryptography, computers, electro‐acoustics, geosciences, instrumentation, and reliability engineering. This article addresses the various noise generation techniques and implementing them in analog and digital circuit technology and concludes with a discussion of typical applications.
