112G SerDes Reliability
By Ed Sperling - 05 Oct, 2020 - Comments: 0

Priyank Shukla, product marketing manager at Synopsys, digs into 112Gbps SerDes, why it’s important to examine the performance of these devices in the context of a system, what is acceptable channel loss, and how density can affect performance, power and noise. » read more

For AI Hardware, Power Optimization Starts With Software And Ends At Silicon
By Solaiman Rahim - 04 Sep, 2020 - Comments: 0

Artificial intelligence (AI) processing hardware has emerged as a critical piece of today’s tech innovation. AI hardware architecture is very symmetric with large arrays of up to thousands of processing elements (tiles), leading to billion+ gate designs and huge power consumption. For example, the Tesla auto-pilot software stack consumes 72W of power, while the neural network accelerator cons... » read more

Semiconductors And The Climate Curve
By Rob Aitken - 13 Aug, 2020 - Comments: 0

On July 22 I participated in a panel at the virtual SEMICON West conference called “Bending the Climate Curve: Enabling Sustainable Growth of Big Data, AI, and Cloud Computing.” Virtual conferences are mandatory these days, but give a different experience than physical ones. They are very good at disseminating information and are reasonably effective at networking. But, in my experience... » read more

A 10.5 μW Programmable SAR ADC Frontend With SC Preamplifier For Low-Power IoT Sensor Nodes
By Fraunhofer IIS/EAS - 12 Aug, 2020 - Comments: 0

Massive deployment of wireless autonomous sensor nodes requires their lifetime extension and cost reduction. The analog frontend (AFE) plays a key role in this context. This paper presents a successive approximation register analog-to-digital converter (SAR ADC) with a switched-capacitor programmable gain switched preamplifier (SC PGSA), as a basic component of an integrated ultra-low power AFE... » read more

Easier Low Power ICs With Reference Flows
By Terence Chen - 09 Jul, 2020 - Comments: 0

By Terence Chen and Alexander Volkov Power-sensitive ICs for wearables and internet of things (IoT) products are in demand for markets ranging from automotive to military/aerospace to consumer. As with most ICs, cost and time-to-market pressures are important determiners of success. Reducing risk by using a vendor-created reference flow can confer a serious business advantage. Reference f... » read more

Designing For Extreme Low Power
By Brian Bailey - 09 Jul, 2020 - Comments: 3

There are several techniques available for low power design, but whenever a nanowatt or picojoule matters, all available methods must be used. Some of the necessary techniques are different from those used for high-end designs. Others have been lost over time because their impact was considered too small, or not worth the additional design effort. But for devices that last a lifetime on a si... » read more

Low-Power Analog
By Brian Bailey - 14 May, 2020 - Comments: 3

Analog circuitry is usually a small part of a large SoC, but it does not scale in the same way as digital circuitry under Moore's Law. The power consumed by analog is becoming an increasing concern, especially for battery-operated devices. At the same time, little automation is available to help analog designers reduce consumption. "Newer consumer devices, like smartphones and wearables, alo... » read more

Security From The Ground Up
By Thomas Ensergueix - 17 Apr, 2020 - Comments: 0

Silicon and system design are complex and costly enough in the ultra-deep sub-micron era. Now factor in security. Virtually every end application requires some level of security, and, as the cybersecurity threat rises, the importance and value of trust and assurance rises as well. This is even more evident in “high-security” use cases such as smart cards used to enter buildings, SIM card... » read more

Designing Ultra Low Power AI Processors
By Ann Mutschler - 09 Apr, 2020 - Comments: 0

AI chip design is beginning to shift direction as more computing moves to the edge, adding a level of sophistication and functionality that typically was relegated to the cloud, but in a power envelope compatible with a battery. These changes leverage many existing tools, techniques and best practices for chip design. But they also are beginning to incorporate a variety of new approaches tha... » read more

Week In Review: Design, Low Power
By Jesse Allen - 07 Feb, 2020 - Comments: 0

Presto Engineering, an outsourced operations provider to semiconductor and IoT device manufacturers, acquired the DELTA Microelectronics business unit of FORCE Technology. The acquisition adds DELTA's ASIC design and manufacturing to its portfolio. The two companies will retain a strong relationship: FORCE Technology has become a shareholder of Presto Engineering and Juan Farré, FORCE’s CTO,... » read more
