A hardware random number generator using Josephson oscillation and a few single flux quantum (SFQ) logic gates is presented. The logic circuit of the random number generator consists of one toggle flip flop and one and gate. A prototype random number

An experimental demonstration and performance estimation of a superconducting relaxation oscillator using the Schmitt trigger inverter are reported. The superconducting Schmitt trigger inverter is composed of a threshold gate that uses coupled superc

We propose a neural network using coupled-SQUIDs to solve the N-Queens problem, a combinatorial optimization problem. The N-Queen problem consists of placing N queens on an N × N chess board such that none of the queens are able to capture any other

We have designed a 2-bit Booth encoder with Josephson Transmission Lines (JTLs) and Passive Transmission Lines (PTLs) by using cell-based techniques and tools. The Booth encoding method is one of the algorithms to obtain partial products. With this m

We have designed and implemented a 4-bit Carry Look-ahead Adder (CLA) and 4-bit parallel multipliers to be used for the Fast Fourier Transform (FFT) system with the estimated clock frequency of 20 GHz. Through some high frequency functional tests, we

We report a design and an experimental result of an SFQ up/down counter for neural computation using stochastic logic. Neural computation using stochastic logic must accumulate the pulses in order to generate the membrane potential of a neuron. A hig

A new relaxation oscillator using a superconducting Schmitt trigger inverter is proposed and tested. The superconducting Schmitt trigger inverter is composed of a threshold gate using coupled superconducting interference devices (SQUIDs). The oscilla

We propose a stochastic neurosystem using SFQ logic circuits and design the main components with the following functions: carrying out the multiplication of an input to a neuron on a synaptic weight value, integrating pulses to generate a membrane po

For the improvement of the phase-mode parallel multiplier, we propose to use a Booth encoder as a substitute of an AND array. Booth's algorithm is often used for the generation of partial products. The scale of the encoder does not matter for definin

We report the preliminary designs and the experimental results of high-speed digital processing elements based on phase-mode logic circuits. The core cell of these elements is a bit-serial adder cell consisting of the ICF gate which is the basic gate
