Stochastic binary networks with asymmetric and time-delayed interactions
Hantao Zhang, Sidra Gibeault, Matthew W. Daniels +4
Stochastic binary networks are widely used to describe collective dynamics in complex systems and to perform neuromorphic computation, yet realistic networks often contain both asy…
CMOS-integrated superparamagnetic tunnel junction-based p-bit
Ju-Young Yoon, Nuno Cacoilo, Advait Madhavan +5
Probabilistic computers offer promising solutions for computationally hard problems in domains such as combinatorial optimization and machine learning. A key building block in thes…
Wafer-Level Prototyping Tools for CMOS Bioelectronic Sensors
Advait Madhavan, Ruohong Shi, Alokik Kanwal +5
Integrating biology with complementary metal-oxide-semiconductor (CMOS) sensors can enable highly parallel measurements with minimal parasitic effects, significantly enhancing sens…
Entropy-Assisted Nanosecond stochastic operation in perpendicular superparamagnetic tunnel junctions
Lucile Soumah, Louise Desplat, Nhat-Tan Phan +7
We demonstrate a good agreement between mean dwell times measured in 50~nm diameter, perpendicularly magnetized superparamagnetic tunnel junctions (SMTJ), and theoretical predictio…
Sampling from exponential distributions in the time domain with superparamagnetic tunnel junctions
Temitayo N. Adeyeye, Sidra Gibeault, Daniel P. Lathrop +8
In the superparamagnetic regime, magnetic tunnel junctions switch between two resistance states due to random thermal fluctuations. The dwell time distribution in each state is exp…
