This paper presents a top-down methodology for designing battery-less systems for the Internet-of-Things (IoT). We start by extracting features from a target IoT application and the environment in which it will be deployed. We then present strategies...
A low-power voltage reference cell for system-on-a-chip applications is presented in this paper. The proposed cell uses a combination of standard transistors and thick-oxide transistors to generate a voltage above 1 V. A design procedure is also pres...
The continuous scaling needed for better performance and higher density has introduced some new challenges to the back end of line (BEOL) in terms of layout and design. Reductions in metal line width, spacing, and thickness require major changes in b...
Energy consumption of processors and memories is quickly becoming a limiting factor in the deployment of large computing systems. For this reason, it is important to understand the energy performance of these processors and to study strategies allowi...
We discuss the impact of physical computing techniques to classifying network security issues for ultra-low power networked IoT devices. Physical computing approaches enable at least a factor of 1000 improvement in computational energy efficiency emp...
This paper presents an on-chip temperature sensor circuit for dynamic thermal management in VLSI systems. The sensor directly senses the threshold voltage that contains temperature information using a single PMOS device. This simple structure enables...
A simple optimization strategy for the computation of 3D finite-differencing kernels on many-cores architectures is proposed. The 3D finite-differencing computation is split direction-by-direction and exploits two level of parallelism: in-core vector...
An ultra-low-power MicroController Unit System-on-Chip (MCU SOC) is described with integrated DC to DC power management and Adaptive Dynamic Voltage Control (ADVC) mechanism. The SOC, designed and fabricated in a 40 nm ULP standard CMOS technology, i...
Performance analysis tools allow application developers to identify and characterize the inefficiencies that cause performance degradation in their codes, allowing for application optimizations. Due to the increasing interest in the High Performance...
This article reviews design challenges for low-power CMOS high-speed analog-to-digital converters (ADCs). Basic ADC converter architectures (flash ADCs, interpolating and folding ADCs, subranging and two-step ADCs, pipelined ADCs, successive approxim...
