Can Analog Make A Comeback?


We live in an analog world dominated by digital processing, but that could change. Domain specificity, and the desire for greater levels of optimization, may provide analog compute with some significant advantages — and the possibility of a comeback. For the last four decades, the advantages of digital scaling and flexibility have pushed the dividing line between analog and digital closer ... » read more

Memory Bandwidth Regulation on Hybrid NVM/DRAM Platforms


New technical paper from Shanghai Jiao Tong University Abstract "Non-volatile memory (NVM) has emerged as a new memory media, resulting in a hybrid NVM/DRAM configuration in typical servers. Memory-intensive applications competing for the scant memory bandwidth can yield degraded performance. Identifying the noisy neighbors and regulating the memory bandwidth usage of them can alleviate th... » read more

Always-On, Ultra-Low-Power Design Gains Traction


A surge of electronic devices powered by batteries, combined with ever-increasing demand for more features, intelligence, and performance, is putting a premium on chip designs that require much lower power. This is especially true for always-on circuits, which are being added into AR/VR, automotive applications with over-the-air updates, security cameras, drones, and robotics. Also known as ... » read more

The Value Of RF Harmonic Balance Analyses For Analog Verification


By Pradeep Thiagarajan and Scott Guyton The world we live in is intricately connected by electronic systems that are expected to function flawlessly to satisfy consumer needs. Functionality violations beyond certain tolerance levels are frowned upon and negatively impact the quality level of products. These systems are required to function accurately, in tandem with other interdependent syst... » read more

Enabling Training of Neural Networks on Noisy Hardware


Abstract:  "Deep neural networks (DNNs) are typically trained using the conventional stochastic gradient descent (SGD) algorithm. However, SGD performs poorly when applied to train networks on non-ideal analog hardware composed of resistive device arrays with non-symmetric conductance modulation characteristics. Recently we proposed a new algorithm, the Tiki-Taka algorithm, that overcomes t... » read more

Wrestling With Analog At 3nm


Analog engineers are facing big challenges at 3nm, forcing them to come up with creative solutions to a widening set of issues at each new process node. Still, these problems must be addressed, because no digital chip will work without at least some analog circuitry. As fabrication technologies shrink, digital logic improves in some combination of power, performance, and area. The process te... » read more

Using 5nm Chips And Advanced Packages In Cars


Semiconductor Engineering sat down to discuss the impact of advanced node chips and advanced packaging on automotive reliability with Jay Rathert, senior director of strategic collaborations at KLA; Dennis Ciplickas, vice president of advanced solutions at PDF Solutions; Uzi Baruch, vice president and general manager of the automotive business unit at OptimalPlus; Gal Carmel, general manager of... » read more

Power/Performance Bits: Jan. 5


Quiet qubits Researchers at the University of New South Wales Sydney recorded the lowest noise levels yet for a semiconductor qubit. Charge noise caused by material imperfections interferes with the information encoded on qubits, reducing accuracy. "The level of charge noise in semiconductor qubits has been a critical obstacle to achieving the accuracy levels we need for large-scale error-c... » read more
